Subject: ste

Perform a correlation test for normality using the P-value approach. The
data to the right were found on the average time, in minutes, spent per
user per month from January to June of one year for a sample of 12 shoe
and apparel retail Web sites. At the 1% significance level, do the data
provide sufficient evidence to conclude that the average time spent per
user per month from January to June of the year in question is not
normally distributed?
State the null and alternative hypotheses.
Ho: Average times spent per user per month are normally distributed.
H₂: Average times spent per user per month are not normally distributed.
Compute the test statistic.
