Complete question:

A consumer products company is formulating a new shampoo and is interested in foam height (in millimeters). Foam height is approximately normally distributed and has a standard deviation of 20 millimeters. The company wishes to test H0: u=175 millimeters versus Ha:u>175 millimeters, using the results of n samples. Find the boundary of the critical region if the type I error probability is $\alpha = 0.01$ and n = 16

186.63

Step-by-step explanation:

Given:

$\alpha = 0.01$

Using the standard normal deviate table:

NORMSINV(0.01) = 2.326

Thus, the Z score = 2.326

To find the critical value if the mean, use the formula:

$\frac{X' - u_0}{\sigma/\sqrt{n}} = Z$

Since we are to find X', Make X' subject of the formula:

$X' = u_0 + (Z * \frac{\sigma}{\sqrt{n}})$

$X' = 175 + (2.326 * \frac{20}{\sqrt{16}})$

X' = 175 + (2.326 * 5)

X' = 175 + 11.63

X' =186.63

The boundary of the critical region is 186.63

(c) compare the results of parts (a) and (b). in general, how do you think the mode, median, and mean are affected when each data value in a set is multiplied by the same constant? multiplying each data value by the same constant c results in the mode, median, and mean increasing by a factor of c. multiplying each data value by the same constant c results in the mode, median, and mean remaining the same. multiplying each data value by the same constant c results in the mode, median, and mean decreasing by a factor of c. there is no distinct pattern when each data value is multiplied by the same constant. (d) suppose you have information about average heights of a random sample of airline passengers. the mode is 65 inches, the median is 72 inches, and the mean is 65 inches. to convert the data into centimeters, multiply each data value by 2.54. what are the values of the mode, median, and mean in centimeters? (enter your answers to two decimal places.) mode cm median cm mean cm in this problem, we explore the effect on the mean, median, and mode of multiplying each data value by the same number. consider the following data set 7, 7, 8, 11, 15. (a) compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = (b) multiply 3 to each of the data values. compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = --
