According to a research study, parents with young children slept 6.5 hours each night last year, on average. A random sample of 15 parents with young children was surveyed and the mean amount of time per night each parent slept was 6.1. This data has a sample standard deviation of 0.7. (Assume that the scores are normally distributed.) Researchers conduct a one-mean hypothesis at the 1% significance level, to test if the mean amount of time parents with young children sleep per night is less than the mean amount of time last year. Which answer choice shows the correct null and alternative hypotheses for this test
