Answer:
The first choice is the one you want
Step-by-step explanation:
Use geometric means to solve for a first. The formula is
and 64 = 15a and a = 64/15
That one was quite easy. Finding b is a bit more difficult.
The formula for finding b is
Solving for b:
Filling in we have
and
and
so b = 136/15
The histogram will have a shape that is left-skewed. Then the correct option is B.
<h3>What is a histogram?</h3>A diagram is made up of rectangles whose size is related to a variable's frequency and whose width is comparable to the training sample.
Students in a fitness class each completed a one-mile walk or run. The list shows the time it took each person to complete the mile. Each time is rounded to the nearest half-minute.
5.5, 6, 7, 10, 7.5, 8, 9.5, 9, 8.5, 8, 7, 7.5, 6, 6.5, 5.5
Then the mean will be
Mean = (5.5 + 6 + ..... + 6.5 + 5.5) / 15
Mean = 111.5/12
Mean = 7.4333
Then the median will be
Median = 7.5
The histogram will have a shape that is left-skewed.
Then the correct option is B.
