A golf association requires that golf balls have a diameter

A golf association requires that golf balls have a diameter that is 1.68 inches. table. Complete parts (a) and (b). To determine if golf balls conform to the standards, a random sample of golf balls was selected t Their diameters are shown in the Click the lcon to view the data table (a) Because the sample size is small, the engineer must verify that the diameter is normally disnbuted and the sample does not contain way outliers. The normal probability plot and below. the sample does not contain any outliers. The normal probability plot and boxplot are shown Click the loon to view the graphs. Are the conditions for testing the hypothesis satisfled? O No O Yes (b) Do the golf balls conform to the standards? Conduct a hypothesis test using the P-value approach and a level of significance of a-0.05 First determine the appropriate hypotheses 1.68

Solution

a) Yes

b) H0: mu=1.68 vs H1: mu not equal to 1.68

c) T= 0.77

d) p-value  0.457

(conclusion-option B)
