Problem 1299

Polyanne, a hospital administrator, noticed a significant change in the weight of babies born at the hospital during the last few months. She randomly selected 20 babies born in the last month and found the weights. Historically, the weight of babies born at the hospital is normally distributed with a population mean weight of 7.63 pounds and a population standard deviation of 1.02 pounds. To test the weights, Polyanne decided to use the historical standard deviation as the population standard deviation. The hospital administrator conducts a one-mean hypothesis at the $5 \%$ significance level, to test if there was a change in the weight of babies being born at the hospital in the last few months from 7.63 pounds. (a) Which answer choice shows the correct null and alternative hypotheses for this test?
Select the correct answer below: $H_{0}: \mu=7.63 ; H_{a}: \mu>7.63$ , which is a right-tailed test. $H_{0}: \mu=1.02 ; H_{a}: \mu<1.02$ , which is a left-tailed test. $H_{0}: \mu=1.02 ; H_{a}: \mu \neq 1.02$ , which is a two-tailed test. $H_{0}: \mu=7.63 ; H_{a}: \mu \neq 7.63$ , which is a two-tailed test.
