Answer:
81.85% of days would you expect the store to sell from 33 to 42 pairs of shoes
Step-by-step explanation:
The mean number of pairs of shoes sold by a shoe store is 36
Standard deviation =
We are supposed to find percent of days would you expect the store to sell from 33 to 42 pairs of shoes i.e.P(33<x<42)
Formula :
At x = 33
Z=-1
Refer the z table for p value
p =0.1587
At x = 42
Z=2
Refer the z table for p value
p =0.9772
So,P(33<x<42)=P(x<42)-P(x<33)=0.9772-0.1587=0.8185
Hence 81.85% of days would you expect the store to sell from 33 to 42 pairs of shoes

Kindly check explanation
Step-by-step explanation:
Calculate the 25th, 50th, and 75th percentiles.
b. Calculate the interquartile range.
c. Construct a boxplot. Are there any outliers?
Reordered data:
25, 40, 52, 55, 60, 70, 70, 72, 74, 75, 75, 80, 80, 85, 85, 86, 87, 90, 92, 99
25 th percentile :
1/4 (n + 1)th, tetm
n = 20
1/4(21) = 5.25th term
(5 + 6) th term / 2
= 65
50th percentile :
1/2 (n + 1)th, tetm
n = 20
1/2(21) = 10.5th term
(10 + 11) th term / 2
= 75
75th percentile:
3/4 (n + 1)th, tetm
n = 20
3/4(21) = 15.75th term
(15 + 16) th term / 2
= 85.5
Interquartile range :
Q3 - Q1
75th percentile - 25th percentile
85.5 - 65
= 20.5
25 is an Outlier
