We would like to test a hypothesis regarding one population mean. The null hypothesis is H0: μ = 31.7. A random sample of size n = 22 is taken and the sample mean is x¯ = 28.9 and the sample standard deviation is s = 6.4. Calculate the value of the test statistic. Enter your answer to two decimal places.
