7.25 Consider the sampling distribution of given in Table 7.5.a. Calculate the value of using the formula Is the value of calculated in Exercise7.6 the same as the value of calculated here?b. Calculate the value of by using the formulac. From Exercise 7.6, 8.09. Also, our sample size is 3, so that n 3. Therefore,From part b, you should get Why does not equalin this case?d. In our example (given in the beginning of Section 7.1) on scores, N 5 and n 3. Hence,nN 35 .60. Because nN is greater than .05, the appropriate formula to find isShow that the value of calculated by using this formula gives the same value as the one calculatedin part b above.
