To check whether ? this is still accurate, heights are measured for a random sample of 17 Begonias grown while being treated with the nutrient. The sample mean and sample standard deviation of those height measurements are 46 centimeters and 9 centimeters, respectively. Assume that the heights of treated Begonias are approximately normally distributed. Based on the sample, can it be concluded that the population mean height of treated begonias, u, is different from that reported in the journal?

A medical researcher believes that, because of ? modern dietary habits, the mean sodium level for healthy adults, u, now differs from that given in the textbook. A random sample of 27 healthy adults is evaluated. The mean sodium level for the sample is 144 mEq per liter of blood. It is known that the population standard deviation of adult sodium levels is 12 mEq. Assume that the population is normally distributed. Can we conclude, at the 0.10 level of significance, that the population mean adult sodium level differs from that given in the textbook? oo Perform a two-tailed test. Then complete the parts below.
