Suppose a professional golfing association requires that the standard deviation of the diameter of a golf ball be less than 0.005 inch. Determine whether these golf balls conform to this requirement at the alpha equals 0.05 level of significance. Assume that the population is normally distributed. 1.678 1.681 1.676 1.684 1.676 1.679 1.681 1.681 1.677 1.676 1.681 1.683 What are the correct hypotheses for this test? The null hypothesis is H0: ▼ sigma p mu ▼ less than equals not equals greater than ▼ 0.002811. 0.005. The alternative hypothesis is H1: ▼ p sigma mu ▼ not equals less than equals greater than ▼ 0.005. 0.002811. Find the sample standard deviation. sequals nothing (Round to five decimal places as needed.) Use s to calculate the value of the test statistic. chi Subscript 0 Superscript 2equals nothing (Round to two decimal places as needed.) Use technology to determine the P-value for the test statistic. The P-value is nothing. (Round to three decimal places as needed.) What is the correct conclusion at the alpha equals 0.05 level of significance? Since the P-value is ▼ greater less than the level of significance, ▼ reject do not reject the null hypothesis. There ▼ is is not sufficient evidence to conclude that these golf balls conform to the requirement at the 0.05 level of significance.
