QUESTION 7Almost all medical schools in the United States require students to take the Medical College Admission Test (MCAT). The exam is composed of of three multiple-choice sections (Physical Sciences, Verbal Reasoning, and Biological Sciences). The score on each section is converted to a 15-point scale so that the total score has a maximum value of 45. The total scores follow a normal distribution. In a random sample of 345 students taking the MCAT the mean score was 27.3. The standard deviation for all students taking the MCAT was 5.9. What is the point estimate for this sample? State the answer and explain how you determined the answer.

QUESTION 7

Almost all medical schools in the United States require students to take the Medical College Admission Test (MCAT). The exam is composed of of three multiple-choice sections (Physical Sciences, Verbal Reasoning, and Biological Sciences). The score on each section is converted to a 15-point scale so that the total score has a maximum value of 45. The total scores follow a normal distribution. In a random sample of 345 students taking the MCAT the mean score was 27.3. The standard deviation for all students taking the MCAT was 5.9.

What is the point estimate for this sample?

State the answer and explain how you determined the answer.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
