Question

Question 24 1 pts A few years ago, people tended to have relatively large CD collections. For students at a large university in the midwest (enrollment = 25,000), the mean number of CDs owned was 78 with a standard deviation of 90. To confirm these numbers, a random sample of 15 students from this university was collected and the size of their CD collections recorded. The mean number of CDs for this sample of students was 67. MusicCDs Count 0 50 100 150 200 250 Based on the histogram of the 15 CD collection sizes provided above and the description of the study, which of the necessary conditions for the sampling distribution of the sample mean to follow a normal model is NOT satisfied in this study? 10% condition Nearly Normal condition Success/Failure condition Randomization condition

Answer 1

Ans:

Correct option is:

Nearly Normal condition

As,from histogram it appears that distribution is right skewed,so nearly normal condition is not satisfied.
