Answer 2

Answer:

Week 4

Step-by-step explanation:

A week consist of 7 days (MO, TU, WE, TH, FR, SA, SU)

The mean of the sells done by the store is calculated as the following:

(MO+TU+WE+TH+FR+SA+SU ) 1/7

If we calculate the mean of every given week we have this

Week 1: 6.57

Week 2: 8.86

Week 3: 2.28

Week 4: 8

Since a typical day the jewelry store sells 8 bracelets, in a typical week, the mean of bracelets sold is 8.

The week 4 is the best estimate of the jewelry store's weekly sales throughout the year.
