The null hypothesis (H0) is the statement that there is no difference between the population mean and the hypothesized value. The alternative hypothesis (H1) is the statement that there is a difference between the population mean and the hypothesized value. In this case, the hypothesized value is 2 hours. The null hypothesis is that the population mean is equal to 2 hours, and the alternative hypothesis is that the population mean is not equal to 2 hours.
