Jerry has taken a random sample of students and determined the number of electives that each student in his sample took last year. There were 19 students in the sample. Here is the data on the number of electives the 19 students took: 6, 6, 8, 7, 7, 7, 8, 9, 10, 8, 7, 6, 9, 6, 8, 7, 9, 7, 10. The mean of this sample data is 7.63. What would the mean be for a different random sample of 19 students from the same population? Answers The second mean would be the same as the first mean. The second mean would be higher than the first mean, but within 1 standard deviation. The second mean would be lower than the first mean, but within 1 standard deviation. There is insufficient data to predict the mean for the second sample.
