For each situation, state the null and alternative hypotheses: (Type "mu" for the symbol u, e.g. mu > 1 for the mean is greater than 1, mu <1 for the mean is less than 1, mu not = 1 for the mean is not equal to 1. ase do not include units such as "mm" or "$* in your answer.) The diameter of a spindle in a small motor is supposed to be 6.5 millimeters (mm) with a standard deviation of 0.18 mm. If the spindle is either too small or too large, the motor will not work properly. The manufacturer asures the diameter in a sample of 15 spindles to determine whether the mean diameter has moved away from the required measurement. Suppose the sample has an average diameter of 6.39 mm, Harry thinks that prices in Caldwell are lower than the rest of the country.

Question

Please see below. I really need help with this. Please read the directions thoroughly as the answers must include mu, the appropriate symbol, and number for answer in them. 

For each situation, state the null and alternative hypotheses: (Type "mu" for the symbol u , e.g. mu > 1 for the mean is greater than 1, mu < 1 for the mean is less than 1, mu not =1 for the mean is not equal to 1. %3D Please do not include units such as "mm" or "$" in your answer.) (a) The diameter of a spindle in a small motor is supposed to be 6.5 millimeters (mm) with a standard deviation of 0.18 mm. If the spindle is either too small or too large, the motor will not work properly. The manufacturer measures the diameter in a sample of 15 spindles to determine whether the mean diameter has moved away from the required measurement. Suppose the sample has an average diameter of 6.39 mm. Ho: Ha: (b) Harry thinks that prices in Caldwell are lower than the rest of the country. He reads that the nationwide average price of a certain brand of laundry detergent is $22.35 with standard deviation $1.27. He takes a sample from 4 local Caldwell stores and finds the average price for this same brand of detergent is $21.32. Ho : H.: thio pnblo Note: Vou can oamn partiel omdit o
