The above operation produces a t-test value of t(53) = 0.7533708035. According to the t-distribution
table in the next page, a level of significance of 5% and a degree of freedom of 7 (
produce a two-sided t-test value of approximately 2.365. Since the calculated t-test value is lower
than the table value, the hypothesis that population mean
