Question
Chapter 5, Problem 20E
a)
To determine
To find which month have highest ozone level ever recorded.
a)
Expert Solution
Answer to Problem 20E
April.
Explanation of Solution
Given:
There is outlier in April which is highest ozone level. Hence, April month having highest ozone level.
b)
To determine
To find which month have largest IQR.
b)
Expert Solution
Answer to Problem 20E
February month have largest IQR.
Explanation of Solution
Given:
The height of the box is largest for February month. Hence, February having largest IQR.
c)
To determine
To find which month have smallest
c)
Expert Solution
Answer to Problem 20E
August having smallest range.
Explanation of Solution
Given:
The distance between the whiskers is small then we supposed that month having smallest range. Therefore, August month have smallest range.
d)
To determine
To compare January and June ozone level.
d)
Expert Solution
Answer to Problem 20E
The center of ozone level in both months are same. But the spread of ozone level in January is more than June.
Explanation of Solution
Given:
The center of ozone level in both months are same. But the spread of ozone level in January is more than June.
e)
To determine
To write a report on annual pattern of ozone levels.
e)
Expert Solution
Explanation of Solution
Given:
The center of ozone level in both months are same. But the spread of ozone level in January is more than June. The distance between the whiskers is small then we supposed that month having smallest range. Therefore, August month have smallest range. Therefore, the ozone levels seem to be higher at the beginning of the year than at the end of the year. They are highest in March and April, while lowest in October.

- A well-known company predominantly makes flat pack furniture for students. Variability with the automated machinery means the wood components are cut with a standard deviation in length of 0.45 mm. After they are cut the components are measured. If their length is more than 1.2 mm from the required length, the components are rejected. a) Calculate the percentage of components that get rejected. b) In a manufacturing run of 1000 units, how many are expected to be rejected? c) The company wishes to install more accurate equipment in order to reduce the rejection rate by one-half, using the same ±1.2mm rejection criterion.
