Transcribed Image Text: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 Ho:µ = 175 millimeters versus Hj:µ>175 millimeters,
using the results of n = 10 samples.
(a) Find the type I error probability a if the critical region is
x>185.
(b) What is the probability of type II error if the true mean
foam height is 185 millimeters?
(c) Find B for the true mean of 195 millimeters.

Transcribed Image Text:a α-0.057053,
ь.В — 0.5,
c. B = 0.057053.
