To test the null hypothesis "the mean weight for adult males equals 160lb" against the alternative " the mean weight for adult males exceeds 160lbs." the weights of 16 males were obtained.
173, 178, 145, 146, 157, 175, 173, 137, 152, 171, 163, 170, 135, 159, 199, 131.
Assume Normality and verify the results shown on the following Minitab analysis by calculating the values yourself.
test of MU = 160.00 vs MU > 160.00
C1 N 16, Mean 160.25, STDEV 18.49, SE MEAN 4.62, T 0.05, P 0.48
Analyze the problem and type a short summary (1-2 paragraphs) of the results.
