Question

The data shows the number of customers Joe's diner serve during lunchtime hours for the past 12 days22,25,50,58,28,24,25,51,43,32,49,38

Answer 1

The dataset consists on the points:

{22,25,50,58,28,24,25,51,43,32,49,38}

Sorting the numbers from lowest to highest:

{22,24,25,25,28,32,38,43,49,50,51,58}

There are 12 numbers, thus the median is the mean of the data 6 and 7:

M = (32+38)/2 = 35

The first point is 22, the last point is 58

The only box plot that follows all the conditions is A, where the median is at 35

Answer: A
