Your sample consists of 45 values, with a sample mean of 54.4. Suppose the population standard deviation is known to be 3.62. a) Calculate the value of the test statistic, rounded to 2 decimal places. = b) At α=0.08, the rejection region is z<−1.41 or z>1.41 z<−1.75 z>1.75 z>1.41 z<−1.41 z<−1.75 or z>1.75 c) The decision is to Accept the alternative hypotheis Reject the nult hypothesis Fail to reject the null hypothesis Accept the null hypothesis d) Suppose you mistakenly rejected the null hypothesis in this problem, what type of error is that? Type II Type 1
