Question

26. Distributions A and B have the same mean and range. The standard deviations of distribution A and distribution B are 15 and 5 respectively We may conclude that: a. the scores in distribution B are grouped closer to the mean than the scores in b. the scores in distribution A are grouped closer to the mean than the scores in c. there are three times as many scores from -1 standard deviation to +1 standard d. there are one-third as many scores from-1 standard deviation to +1 standard deviation e. cannot say unless we know the value of the mean 27. A given normal distribution has a mean of 0. What would be the area under the normal distribution A distribution B. deviation in distribution A in distribution curve that is less than the mean?

Explanation / Answer

Q26) Option A is Correct because the scores in distribution B are more closer to the mean because of less standard deviation

Q27) The area will be 0.50
