28 miles per hour is your answer 154 divided by 5.5, simple math hon :) good luck.
Answer:
D.) Median for both bakeries because the data is not symmetric
Step-by-step explanation:
You can compare box-and-whisker plots for the two bakeries
.
Neither bakery has a normal distribution.
The median for Bakery A is not in the middle of the box.
Rather, it cuts the box into two unequal parts, so the data does not have a normal distribution.
The longer part is below the median, so the data are skewed to the bottom.
Similarly, the data for Bakery B are skewed to the top.
The values in the tails pull the mean down for Bakery A and up for Bakery B, so it is better to describe the centres of distribution in terms of the medians.
start at 2 and go up 1 and over 1/2
We know that:
Mean = 82 mm and SD = 10 mm ( standard deviation )
82 - 3 * SD = 82 - 3 * 10 = 82 - 30 = 52 mm
82 + 3 * SD = 82 + 3 * 10 = 82 + 30 = 112 mm
Population between 52 and 112 mm is within +/- 3 standard deviations from the mean.
By the 66- 95 - 99.7 % rule it is: 99.7% of the test group.
0.977 * 500 = 498.5
Answer:
99.7 % of the test group have a diastolic pressure between 52 and 112 mm, or 498 men.
