A quality control analyst is verifying that the 1 lb bags of coffee are indeed 16 oz. He knows if it is different than 16 oz. he will have to shut down the machine and recalibrate it. His hypotheses are: Ho : 1 = 16oz. Ha: μ# 16oz. Each hour he selects 30 bags and calculates the average. His latest test statistic is 1.68, and his P-value is 0.093. Using a significance level of a = 5%, what is his conclusion? Reject Ho. u is different than 16 oz. O Fail to reject, Ho, you cant prove that u is not different than 16 oz. O Accept Ha. H is not different than 16 oz. Fail to reject, Ho, you cant prove that u is different than 16 oz.

The difference in the observed neurological disease rate, xbar, for a sample of veterans who served in Iraq is not  “statistically significantly different” (alpha = .05), from the overall population disease rate for all U.S. veterans, mu0. This means: a. xbar = mu0b. The disease rates xbar and mu0 are not equal, but the size of the difference is not practically important, not big enough to matter. c. H0: mu for Iraq vets =  mu0   was not rejected  d. None of the above

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…
