Can someone check this

Question

Exam scores from a previous STATS 200 course are normally distributed with a mean of 74 and standard deviation of 2.65. Approximately 95% of its area is within:

a. One standard deviation of the mean

b. Two standard deviations of the mean

c. Three standard deviations of the mean

d. Depends on the number of outliers

e. Must determine the z-scores first to determine the area

 

Wouldn't this answer be two standard deviations of the mean. Sine the one standard would be 68% while the third would be 99.7%.

Answer 1

B, because the area under the standard normal curve between ±2σ is 0.9545
