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 H₁: > 175 millimeters, using the results of n samples. Find the boundary of the critical region if the type I error probability is a = 0.03 and n = 25.

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 Ho : 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 a = 0.03 and n = 25.
Round your intermediate values to two decimal places. Round your answer to one decimal places (e.g. 98.76).
