Suppose the data represent the inches of rainfall in April for a certain city over the course of 20 years. (a) Determine the quartiles (b) Compute the interquartile range, IQR. (c) Determine the lower and upper fences. Are there any outliers, according to this criterion? (a) What are the quartiles? (Round to three decimal places as needed.) (Round to three decimal places as needed.) Round to three decimal places as needed.) (b) IQR = Round to three decimal places as needed.) (c) The lower fence is (Round to three decimal places as needed.) The upper fence is (Round to three decimal places as needed.)

Solution

excel is used for the analysis.

Q1=1.846

Q2=3.495

Q3=4.955

b) IQR=3.108

c) upper frnce is Q3+1.5*IQR=9.6163

The lower fence is Q1-1.5*IQR=-2.8137

No all the values are between the upper and lower fences.

There are no outliers.
