Based on the null hypotheses, the type of error is Decrease the significance level to decrease the probability of Type I error.

What does null hypotheses means?

In math, null hypotheses refers a type of statistical hypothesis that proposes that no statistical significance exists in a set of given observations.

Here we have give that researchers are testing a new diagnostic tool designed to identify a certain condition. the null hypothesis of the significance test is that the diagnostic tool is not effective in detecting the condition. for the researchers, the more consequential error would be that the diagnostic tool is not effective, but the significance test indicated that it is effective.

And we need to find in which of the following should the researchers do to avoid the more consequential error.

According to the given question, the null hypothesis is that the new diagnostic tool is not effective in detecting the condition.

Here the more consequential error described is that the diagnostic tool is not effective, but the significance test indicated that it is effective. This is a type I error.

And in Hypothesis testing, a type I error involves rejecting the null hypothesis and accepting the alternative hypothesis when in reality, the null hypothesis is true.

Therefore, it involves saying there is significant evidence to show that the new diagnostic tool is effective in detecting the condition when in reality, it isn't.

When the level of significance (α) of a hypothesis test directly gives the probability of a type I error. So, by setting it lower, we reduce the chances of a type I error.

Answer:

The equation of the line is in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

From the given equation, we can see that the y-intercept is 19. This means that the line passes through the point (0, 19).

Therefore, the coordinates of the y-intercept are (0, 19).

The y-intercept of the equation y=6x+19 is the value of y when x equals 0, which is at the point (0,19).

Therefore, in the equation y=6x+19, the y-intercept is at the point (0, 19). Hence, the coordinates of the y-intercept are (0,19).

Based on the information given about the combination, the number of different parts of fruits that can be selected from the bowl will be 6.

Since the bowl contains an apple, a plum, a pear, and a banana, the different pairs of fruit that can be selected from the bowl will be 4C2.

We can solve this further which will be:

= 4C2

= 4! /2! (4 - 2)!

= 4! / 2!2!

= (4 × 3 × 2)/ 2 × 2

I took the quiz on edge 2020.

Using the general formula to get unit vectors in the same direction as a vector V:

v = V/|V|

We will get the unit vector:

v = (−6i + 2j − k)/√41

Here we want to find a versor (also called a unit vector) that has the same direction as the vector:

V = −6i + 2j − k

The general way to find a unit vector, let's call it v, for a given vector V, is:

v = V/|V|

Where |V| is the magnitude of the vector.

In this case, the magnitude will be:

|V| = √( (-6)^2 + 2^2 + (-1)^2) = √( 36 + 4 + 1) = √41

Then the unit vector that has the same direction as the given vector is:

v = (−6i + 2j − k)/√41

Given:

square with sides 10 x 10

circle with radius 5 units.

shape is 3/4 square and 1/4 circle.

Find: perimeter and area of the figure

Solution:

Let's solve the perimeter first.

The perimeter of a square is four times the side of its length,

Since the length of the side is 10 units, the perimeter of the full square is:

Since the figure is only 3/4 square, then the perimeter of the square part of the shape is 3/4 times 40 units = 30 units only.

Now, let's solve for the circumference of the circle. Formula is:

Radius of the circle is 5 units and π ≈ 3.14. Let's plug this in to the formula.

Hence, the circumference of the circle part is 7.85 units only.

Therefore, the perimeter of the figure is 30 units + 7.85 units = 37.85 units or approximately 38 units.

Let's now solve for the area.

Let's solve the area of the full square first then, multiply the answer to 3/4 since our figure is only 3/4 square.

Now, let's solve for the area of the circle part. We will use the area for circle formula then, multiply it to 1/4 since the figure is only 1/4 circle.

The area of the 3/4 square is 75 sq units while the area of the 1/4 circle is 19.625 sq units, hence, the total area of the figure is (75 + 19.625) 94.625 square units or approximately 95 square units.

The correct word to fill in the blank that describes FBE in the circle C given is defined as: D. major arc.

In geometry, a major arc is an arc of a circle that spans more than 180 degrees or half of the circle's circumference. It is larger than a minor arc, which spans less than 180 degrees.

A major arc can also be defined as the complement of a minor arc with respect to the diameter of the circle.

Thus, arc FBE spans more than 180 degrees and it is more than half of the circle shown in the image, therefore, it is described as: D. major arc.

Answer:

Step-by-step explanation:

The text is a statistics problem that asks to find the probability of a certain range of values in a normal distribution. A normal distribution is a bell-shaped curve that shows how data values are spread around the mean. The mean is the average of all the data values, and the standard deviation is a measure of how much the data values vary from the mean. To solve this problem, we can use the following steps:

Convert the given range of values to standard scores or z-scores. A z-score tells us how many standard deviations a value is away from the mean. To find the z-score, we use the formula: z=σx−μ​

where x is the value, μ is the mean, and σ is the standard deviation. For example, to find the z-score for 33.5 psi, we plug in the values: z=233.5−35​=−0.75

This means that 33.5 psi is 0.75 standard deviations below the mean. Similarly, to find the z-score for 36 psi, we plug in the values: z=236−35​=0.5

This means that 36 psi is 0.5 standard deviations above the mean.

Use a z-table to find the area under the curve for each z-score. A z-table is a table that shows the probability of getting a z-score less than or equal to a given value. For example, to find the area under the curve for -0.75, we look up the row for -0.7 and the column for 0.05 in the z-table and get 0.2266. This means that there is a 22.66% chance of getting a z-score less than or equal to -0.75. Similarly, to find the area under the curve for 0.5, we look up the row for 0.5 and the column for 0 in the z-table and get 0.6915. This means that there is a 69.15% chance of getting a z-score less than or equal to 0.5.

Subtract the smaller area from the larger area to find the area between the two z-scores. This area represents the probability of getting a value between 33.5 and 36 psi in the normal distribution. For example, to find the area between -0.75 and 0.5, we subtract: 0.6915−0.2266=0.4649

This means that there is a 46.49% chance of getting a value between 33.5 and 36 psi in the normal distribution.

Multiply the area by 100 to convert it to a percentage and write it with the appropriate units: The percentage of tires that are inflated to a pressure between 33.5 and 36 psi is 0.4649×100=46.49%
