Transcribed Image Text:b-2. Find the p-value.
O pvalue < 0.01
O pvalue 0.10
O 0.05 p-value <0.10
O 0.025 B p-value <0.05
O 0.01B p-value <0.025
C. At the 1% significance level, what is the conclusion?
O Reject Hg, there is enough evidence to support the claim that the data are not normally distributed.
O Do not reject Hg; there is enough evidence to support the claim that the data are not normally distributed.
O Do not reject Hg, there is not enough evidence to support the claim that the data are not normally distributed.
O Reject Ho, there is not enough evidence to support the claim that the data are not normally distributed.

a. Using the goodness-of-fit test for normality, specify the competing hypotheses in order to determine whether or not the data are
normally distributed.
O Ho: The data are normally distributed with a mean of 17.0 and a standard deviation of 7.4.; HA The data are not normally
distributed with a mean of 17.0 and a standard deviation of 7.4.
O Ho: The data are not normally distributed with a mean of 17.0 and a standard deviation of 74.; HA The data are normally
distributed with a mean of 17.0 and a standard deviation of 7.4.
