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 Họ : µ = 175 millimeters versus H1 : µ > 175 millimeters, using the results of n samples. Find the boundary of the critical region if the type error probability is a = 0.05 and n = 4. Round your intermediate values to two decimal places. Round your answer to one decimal places (e.g. 98.76).

Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
