A sample mean, sample size, and sample standard deviation are provided below. Use the one-mean t-test to perform the required hypothesis test at the 1% significance level. x=27 s=4 n=24 H0: u=27 Ha: u>27 what is the test statistic?

If the standard deviation of a population is known and we wish to estimate the population mean with 99% confidence, what is the appropriate critical value 'z' to use? 2.58 2.33 1.96 1.645 1.28
