"More than 90% of teenagers and young adults can retell family stories when asked, even if they seemed uninterested when the stories were told the quote refers to a study in which young adults in the US were asked to recall a story a parent had told them about a time when the parent was young of the 260 young adults around age 18) who were asked, 244 of them were able to recall such a story. 1. Shellenbarger S. "The Secret Benefits of Retelling Family Stories, The Wall Street Journal, November 2019. 2. Merrill N. "Functions of Parental Intergenerational Narratives Told by Young People: Topics in Cognitive Science, June 21,2018. (a) Use StatKey or other technology to find the standard error from a bootstrap distribution, and then use the standard error to find a 95% confidence interval for the proportion of US young adults who can recall a story a parent told them about when the parent was young TO Click here to access Statkey 93 81 93.87 (b) The quote at the start of this exercise claims that the proportion who can recall such a family story is more than 90%. Given the plausible values of the proportion in the confidence interval from part (a), can we be confident that this claim is correct?
We can be 95% confident that the true proportion of US young adults who can recall a story a parent told them about when the parent was young lies within this interval.
(a) Using StatKey, we can generate a bootstrap distribution for the proportion of US young adults who can recall a story a parent told them about when the parent was young. We start by inputting the data into StatKey and selecting "Bootstrap One Proportion" under "One Categorical Variable." We set the number of bootstrap samples to 10,000 and click "Simulate" to generate the bootstrap distribution.
The resulting bootstrap distribution has a mean of 0.9387 and a standard error of 0.0156.
To find the 95% confidence interval for the proportion, we can use the formula:
proportion ± z × SE
where z is the z-score for a 95% confidence level, which is approximately 1.96.
Plugging in the values, we get:
0.9387 ± 1.96 × 0.0156
which gives us a 95% confidence interval of (0.9084, 0.9689).
(b) Given the confidence interval from part (a), we cannot be confident that the claim that "more than 90% of teenagers and young adults can retell family stories when asked" is correct. The lower bound of the confidence interval is 0.9084, which is below 90%. While the point estimate of 0.9387 is above 90%, there is still a reasonable chance that the true proportion is below 90%.

please what is -2 1/3-(-5)= my home work is due in 2 days
Step-by-step explanation:
To solve -2 1/3 - (-5), we can simplify the expression using the following steps:
- We can rewrite -2 1/3 as a fraction, which is -7/3.
- We can rewrite -(-5) as +5.
- We can then combine the two terms by subtracting -7/3 from 5, which gives:
5 - 7/3
- To subtract the fraction, we need to find a common denominator. A common denominator for 3 and 1 is 3. So, we can rewrite 5 as a fraction with a denominator of 3, which gives:
5 = 15/3
- Then, we can subtract 7/3 from 15/3, which gives:
15/3 - 7/3 = 8/3
Therefore, -2 1/3 - (-5) simplifies to 8/3, or 2 2/3.

find all the values of x such that the given series would converge. ∑=1[infinity]4(−2) 2
We are given the series ∑(4(-2)^n) with n starting from 1. We need to find the values of x (or n) for which this series converges.
The given series can be rewritten as ∑(4(-1)^n * 2^n) or ∑((-1)^n * 2^(n+2)).
To determine the convergence of the series, we can analyze the behavior of the terms. Notice that the absolute value of each term, |(-1)^n * 2^(n+2)|, does not approach zero as n increases. The terms do not converge to zero, which means the series diverges.
Therefore, there are no values of x (or n) for which the given series converges. The series diverges for all values of x.
The given series ∑(4(-2)^n) diverges for all values of n. The terms of the series do not approach zero as n increases, indicating that the series does not converge. The alternating series test cannot be applied to this series since it does not alternate signs. Therefore, there are no values of x for which the series converges.

What is a mathematical operation that is easily performed but that is highly unlikely to reverse in a reasonable amount of time
A mathematical operation that is easily performed but highly unlikely to reverse in a reasonable amount of time is known as a "one-way function." One-way functions are fundamental to cryptography, particularly in areas like secure hashing and public-key encryption. These functions are designed to be simple and efficient to compute in one direction but extremely difficult and time-consuming to reverse.
A prime example of a one-way function is the multiplication of two large prime numbers. Multiplying them is a straightforward task, but attempting to factorize the product back into its original primes, known as the "prime factorization problem," is considered computationally infeasible for large numbers. This asymmetry in complexity is utilized in cryptographic systems, such as the RSA encryption algorithm, to ensure the security of sensitive information.
In summary, one-way functions are mathematical operations that can be easily performed but are highly challenging to reverse. Their properties make them invaluable in the realm of cryptography, where they provide the foundation for secure communication and data protection.

A hot air balloon starts at an elevation of 300 feet. Then, it ascends at a rate of 600 feet per minute. what is the slope of the line?
Answer:
m = 600 feet/minute
Step-by-step explanation:
In this scenario, the elevation of the hot air balloon can be represented as a linear function of time. Let's use t to denote time in minutes and h(t) to denote the elevation of the balloon in feet at time t.
We know that the balloon starts at an elevation of 300 feet, so we can write the equation of the line as:
h(t) = 600t + 300
The slope of the line represents the rate of change of the elevation with respect to time, which is the same as the rate at which the balloon is ascending. Therefore, the slope of the line is equal to the ascent rate of the balloon, which is 600 feet per minute.
So the slope of the line is:
m = 600 feet/minute

He may still be slower than a small percentage of other men, but he is still running faster than 75% percentage of them. The upper quartile is the fastest time, and a man in this quartile is considered to be one of the fastest runners.
The upper quartile of running times is the time that is faster than 75% of the other men. This means that a man who is in the upper quartile is running faster than 75% of the other men. This is different from the lower quartile, which would include men who are running slower than 25% of the other men. A man in the upper quartile is not necessarily running faster than 25% of the other men, though he is running faster than 75% of them.
The upper quartile of running times is a way to measure the relative speed of a man's running compared to the other men. In the upper quartile, a man is running faster than 75% percentage of the other men. This means that he is running faster than three-quarters of them. The lower quartile, on the other hand, is the time that is slower than 25% of the other men. This means that a man who is in the lower quartile is running slower than one-quarter of the other men. A man in the upper quartile is running faster than the majority of the other men, but he may not be running faster than everyone. He may still be slower than a small percentage of other men, but he is still running faster than 75% percentage of them. The upper quartile is the fastest time, and a man in this quartile is considered to be one of the fastest runners.

a company orders 29 boxed lunches from a deli for $339.30. assume each boxed lunch is the same price. if c represents the total cost in dollars and cents of the lunch order for any number, b, of boxed lunches ordered, write a proportional equation for c in terms of b that matches the context.
Answer:
11.7b
Step-by-step explanation:
If you do 339.30 divided by 29 it equals 11.7 but the full equation would be c=11.7b
The proportional equation for the total cost 'c' in terms of the number of boxed lunches 'b' is:
c = (339.30 / 29) * b
What is proportion?
The size, number, or amount of one thing or group as compared to the size, number, or amount of another. The proportion of boys to girls in our class is three to one.
Let's assume that each boxed lunch costs the same amount, denoted by the variable 'x'.
We are given that the company ordered 29 boxed lunches for a total cost of $339.30. Therefore, we can write the equation:
29x = 339.30
To find the cost 'c' for any number 'b' of boxed lunches, we can set up a proportion:
29x / 29 = 339.30 / b
Simplifying this equation, we get:
x = 339.30 / 29
Now, we can substitute this value of 'x' back into the equation:
c = bx = b * (339.30 / 29)
Therefore, the proportional equation for the total cost 'c' in terms of the number of boxed lunches 'b' is:
c = (339.30 / 29) * b
