Suppose that you are testing the hypotheses $H_{0}??=17$ v5. $H_{A}?>17$. A sample of size 16 results in a sample mean of 16.5 and a sample standard deviation of 23. a) What is the standard ertor of the mean? b) What is the critical value of $t_{?}$ for a $99%$ confidence interval? c) Construct a $99%$ confidence interval for $?$ d) Based on the confidence interval, at $a=0$ o0s can you rejoct $H_{0}$ ? Explain

ANSWERa) The standard error of the mean (SEM)is given by the formula:SEM=snwhere s is the sample standard deviation, n is the sample size. Substitutin
