A consumer products company is formulating a new shampoo and is interested in foam height (in mm). Foam height is approximately normally distributed and has a standard deviation of 20 mm. The company wishes to test H0: μ = 175 mm versus H1: μ > 175 mm, using a random sample of n = 10 samples. (a) Find P-value if the sample average is Upper X over Bar = 185? Round your final answer to 3 decimal places. (b) What is the probability of type II error if the true mean foam height is 200 mm and we assume that α = 0.05? Round your intermediate answer to 1 decimal place. Round the final answer to 4 decimal places. (c) What is the power of the test from part (b)? Round your final answer to 4 decimal places.

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
25 mm. The company wishes to test Ho:u = 175 mm versus H¡:u >
175 mm, using the results of =15 samples.
(a) Find the type I error probability (alpha) if the critical
region is x>185.
(b) What is the probability of type II error if the true mean

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:μ=175 millimeters
versus H1:μ>175 millimeters, using the results of n
samples. Find the boundary of the critical region if the type I
error probability is α=0.05 and n=16.
Round your intermediate values to two decimal places. Round your
answer to one decimal places (e.g....

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 true standard
deviation of σ=25 millimeters. The company wishes to test
if the true mean foam height exceeds 175 millimeters for
the new shampoo. They took a sample of 15, and the sample
average was found to be 185 millimeters.
What is the type of statistical test procedure that should be
used to test...
