b. 50%
c. 68%
d. 81.5%

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
