5. A random sample of 17 observations from a population has a mean of 25.2 with a standard deviation of 4. If one more observation is to be selected from the population, find a 90% prediction interval for the observation to be selected. (Using t-table for the solution) a. The 90% prediction interval is (24.23, 26.17). b. The 90% prediction interval is (21.08, 29.32). c. The 90% prediction interval is (18.01, 32.39). d. The 90% prediction interval is (23.45, 26.95).
