A school principal gives an IQ test to an random sample of 60 students in her school of the over 1000 students. The mean IQ score was 114.98 and the standard deviation was 14.80. Construct and interpret a 95% confidence interval for the mean IQ score of the students in the school. 5. The information tells us that the survey is a random sample. Show that this situation satisfies the following conditions: a. Show that this situation satisfies the 10% condition. (1 points) b. Show that this situation satisfies the Normal/Large sample condition. (1 points) 6. The general formula used to create a confidence interval is: Statistic † (critical value) (standard deviation of statistic) a. What is the statistic (or point estimate) in this example? (1 points) b. What is the critical value (rounded to 4 decimal places) to determine the confidence interval? (1 points) c. What is the standard deviation of the statistic? (2 points) 7. Calculate a 95% confidence interval for the mean IQ score of the students in the school.(2 points)
