Common C Practice Test 3 ~ Ch 8 - 9 Dionne Question 6 of 33 (1 point) | Question Attempt: 1 of 1 Espa = 1 8 9 10 11 Don't construct a confidence interval: A psychology professor at a certain college gave a test to the students in her class. The test was designed to measure students' attitudes toward school, with higher scores indicating a more positive attitude. There were 30 students in the class, and their mean score was 78. Scores on this test are known to be normally distributed with a standard deviation of 10. Explain why these data should not be used to construct a confidence interval for the mean score for all the students in the college. O The sample size is too small, and we do not know the population is approximately normal. O The sample is not randomly selected to represent the students in the college. This is proportion data, not.mean data. O The standard deviation is too small relative to the mean. 5 X
