question 83

Multiple Choice

From a sample of size 100, the following descriptive measures were calculated: median = 23, mean = 20, standard deviation = 5, range = 35; seventy-five sample values are between 10 and 30; and ninety-nine sample values are between 5 and 35. If you knew the sample mean, median, and standard deviation were correct, which one of the following conclusions might you draw?

• A) The distribution is skewed to the right because the median exceeds the mean.
• B) The range must have been calculated incorrectly because it should not be seven times the standard deviation's value.
• C) The number of sample values between 10 and 30 was miscounted.
• D) The number of sample values between 5 and 35 must have been miscounted because all 100 values must be in this interval.
• E) All of these.
