Question: (1 point) The sample mean and standard deviation from a random sample of 29 observations from a normal population were computed as x = 22

(1 point) The sample mean and standard deviation from a random sample of 29 observations from a normal population were computed as x = 22 and s = 8. Calculate the t statistic of the test required to determine whether there is enough evidence to infer at the 5% significance level that the population mean is greater than 20. Test Statistic =
