(a) Compute the value of the test statistic. A sample of 58 items provided a mean of x = 13 and a standard deviation of s = 6.5. The hypotheses are given below. Hoi u = 14 14 A t test statistic will be used when the standard deviation is calculated from a sample instead of the population. Recall that the test statistic, t, for a hypothesis is calculated as follows where x is the sample mean, is the hypothesized population mean, s is the population standard deviation, and n is the sample size. o x - o t = S n The value for Ho is the hypothesized population mean we are testing for. Here, we have o HO = There was a sample of 58 items given, so we have n = Submit Skip (you cannot come back)
