The intervals suggest that both income and the age of the oldest family automobile are significantly associated with the odds of buying a new car.
How to explain the hypothesis
a. The confidence intervals for the odds ratio of buying a new car for families whose incomes differ by 20 thousand dollars and for the age of the oldest family automobile are as follows:
Income: (1.25, 3.75)
Age of oldest automobile: (1.10, 1.90)
These intervals suggest that both income and the age of the oldest family automobile are significantly associated with the odds of buying a new car.
b. The Wald test for whether X2, age of oldest family automobile, can be dropped from the regression model is as follows:
Test statistic = 2.25
P-value = 0.13
Since the P-value is greater than 0.05, we cannot reject the null hypothesis that X2 does not have a significant effect on the odds of buying a new car. Therefore, we cannot conclude that X2 can be dropped from the regression model.
c. The likelihood ratio test for whether X2, age of oldest family automobile, can be dropped from the regression model is as follows:
Test statistic = 2.25
P-value = 0.13
This result is identical to the result obtained for the Wald test in part (b). This is because the Wald test and the likelihood ratio test are asymptotically equivalent, meaning that they will have the same distribution as the sample size gets larger.
d. The likelihood ratio test for whether the following three second-order terms, the square of annual family income, the square of the age of the oldest family automobile, and the interaction between income and age, can be dropped from the regression model is as follows:
Test statistic = 12.6
P-value = 0.002
Since the P-value is less than 0.05, we can reject the null hypothesis that these three terms do not have a significant effect on the odds of buying a new car. Therefore, we can conclude that these three terms cannot be dropped from the regression model.

Vocational colleges often:
A. take longer to graduate from.
O B. require students to move far from home.
C. save students money, compared with a four-year college.
D. have few teachers.
Answer:
c
Explanation:
Vocational collages often let you graduate earlier then a regular in person collage. The average cost in a vocational school costs 33,000, which is the same cost of a single year of college; saving a hella lot. I highly doubt Vocational schools have less teachers and online schools exist so....
Vocational Colleges Save students money, compared with a four-year college. Therefore, option (B) is correct.
Vocational colleges, also known as trade schools or technical colleges, typically offer hands-on training in a specific trade or skill. These programs are usually shorter in duration than traditional four-year colleges and universities, which can save students money on tuition and other expenses.
Additionally, vocational colleges may offer more affordable options for housing, transportation, and other expenses. While some vocational colleges may require students to move away from home, this is not always the case, and many vocational programs are available in local communities or online, allowing students to study from home.

In a recent poll, 13% of all respondents said that they were afraid of heights. Suppose
this percentage is true for all Americans. Assume responses from different individuals are
independent.
What is the probability of having NONE of the 3
randomly selected Americans say that they are afraid of
heights? Find P(3 people NOT afraid of heights).
A) The probability of 3 randomly selected Americans saying they are afraid of heights is 0.21%.
B) The probability of having none of the 3 randomly selected Americans say they are afraid of heights is 65.85%.
C) The probability of having at least 1 of the 3 randomly selected Americans say they are afraid of heights is 9.83%.
Given that in a recent poll, 13% of all respondents said that they were afraid of heights, supposing this percentage is valid for all Americans and responses from different individuals are independent, to determine A) what is the probability of having 3 randomly selected Americans all say that they are afraid of heights; B) what is the probability of having none of the 3 randomly selected Americans to say that they are afraid of heights; and C) what is the probability of having at least 1 of the 3 randomly selected Americans say that they are afraid of heights; the following calculations must be performed:

The breaking strengths of cables produced by a certain manufacturer have a standard deviation of 92 pounds. A random sample of 90 newly manufactured cables has a mean breaking strength of 1700 pounds. Based on this sample, find a 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer. Then give its lower limit and upper limit. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place
Answer:
To find the 95% confidence interval for the true mean breaking strength of all cables produced by the manufacturer, we can use the formula:
Confidence Interval = Sample Mean ± (Critical Value * Standard Error)
First, let's calculate the standard error, which is the standard deviation divided by the square root of the sample size:
Standard Error = Standard Deviation / √(Sample Size)
= 92 / √(90)
≈ 9.685
Next, we need to determine the critical value corresponding to a 95% confidence level. Since the sample size is large (n > 30), we can use the z-table. The z-value for a 95% confidence level is approximately 1.96.
Now we can calculate the confidence interval:
Confidence Interval = Sample Mean ± (Critical Value * Standard Error)
= 1700 ± (1.96 * 9.685)
Lower Limit = 1700 - (1.96 * 9.685)
≈ 1679.69
Upper Limit = 1700 + (1.96 * 9.685)
≈ 1720.31
Therefore, the 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer is approximately (1679.7, 1720.3). The lower limit is 1679.7 pounds, and the upper limit is 1720.3 pounds.

Ella had two pieces of wire of equal length. She shaped one
piece into a square and the other into an equilateral triangle.
A side length of the triangle was 2 cm longer than a side length
of the square. How long is each piece of wire, in cm?
Each piece of wire, given the shapes that are a square and an equilateral triangle, are 24 cm long.
How to find the length ?Since Ella used the same length of wire to make both shapes, the perimeter (total length of wire) of the square is equal to the perimeter of the triangle.
A square has four equal sides and an equilateral triangle has three equal sides.
4s = 3t
Given that the side length of the triangle is 2 cm longer than the side length of the square:
t = s + 2 (equation 2)
substitute equation 2 into equation 1:
4s = 3(s + 2)
4s = 3s + 6
4s - 3s = 6
s = 6
Substitute s = 6 into equation 2 to find t:
t = 6 + 2
t = 8

Nathan has $700 to deposit into two different savings accounts. • Nathan deposits $350 into Account I, which earns 5% simple interest. • Nathan deposits $350 into Account Il, which earns 5% interest compounded annually. o Which account earns more interest at the end of 4 years?
Not that at the end of 4 years, Account II earns more interest, with a total of $182.88 compared to $70 earned by Account I.
What is the explanation for the above response?To compare the two accounts, we need to calculate the interest earned by each account after 4 years:
• Account I:
Simple Interest = Principal * Rate * Time
= $350 * 0.05 * 4
= $70
• Account II:
Compound Interest = Principal * (1 + Rate/ n)^(n * Time) - Principal
= $350 * (1 + 0.05 / 1)^(1 * 4) - $350
= $182.88
So, at the end of 4 years, Account II earns more interest, with a total of $182.88 compared to $70 earned by Account I. This is because compounding the interest annually allows for interest to be earned on the interest previously earned, resulting in a higher overall return.
