List or circle your sample of 10 values. 59.4 71.6 69.3 65.0 62.9 66.5 61.7 55.2 67.5 67.2 53.8 62.9 63.0 63.9 68. 65.5 (b) Calculate the sample mean and the sample standard deviation. Assume that the population standard deviation is 61.9 69.6 58.7 63.4 61.8 60.6 69.8 60.0 known to be 3.3 inches. 64.9 66.1 66.8 50.6 65.6 63.8 61.3 159.2 64. 59.3 64.9 62.4 .5 60.9 63.3 66.3 61.5 64.3 62.9 60.6 63.8 58.8 64.9 65.7 (c) With these values, construct a 90% confidence interval for 63. 62.2 64.7 56.0 your sample of ten values.
