Directions: Solve for the t-score of the following problems: 1. Suppose a population has mean 80 and standard deviation 10. Then we get a sample of 25 cases and the mean of this sample is 82. Find the t - score if the sample is 25 cases. Answer: 2. The mean weight of a banana is 92 grams with a standard deviation of 6 grams. A sample of 16 is taken from a basket and the mean weight of the sample is 94 grams. Find the t- score of the sample bananas. Answer: Statistics and Probability Q3_W9| 1
