QUESTION 16 The health of employees is monitored by periodically weighing them. A sample of 27 employees has a mean weight of 183 lb and a standard deviation c 41.5 lb. At a significance level 5%, we want to test the claim that the population mean of all such employees weights is less than 200 lb. Which test woul be appropriate for this problem? Either one-sample z-test or one-sample t-test. Neither one-sample z-test nor one-sample t-test. One-sample z-test. One-sample t-test.

QUESTION 15 Oasis Company bottles soft drinks using an automatic filling machine. When the process is running properly, the mean fill is 450 ml per can. Each day. the company selects a random sample of 25 cans yields a mean of 453.85 ml and the standard deviation is 7.5 ml?. They then test to determine whether the filling process is working properly. Suppose that the population is normal. At which significance level a, the null hypothesis is not rejected. 2% 1.5% 03% Ⓒ2.5%
