Answer

Explanation:

Step1: Find frequency for 26 - 35 age group

From the histogram, the frequency for the interval starting at 26 (the bar corresponding to the class starting at 26) up to but not including 35 is 83.

Step2: Calculate number of students under 46

Sum the frequencies of age - groups 16 - 25, 26 - 35, 36 - 45. Frequencies are 389, 83, 27 respectively. So, $389 + 83+27=499$.

Step3: Determine shape of distribution

The histogram has a long - tail on the right side (higher ages have lower frequencies), so it is skewed right.

Answer:

What is the frequency of the 26 - 35 age group? 83 How many students were under the age of 46? 499 What is the shape of the distribution of the Age data? Skewed right
