To determine which week would be a good estimate of the jewelry store's weekly sales throughout the year, we need to calculate the mean (average) number of bracelets sold for each week.
Week 1: (7 + 8 + 7 + 9 + 1 + 6 + 8) / 7 = 6.43 bracelets
Week 2: (6 + 7 + 8 + 7 + 9 + 8 + 17) / 7 = 9.29 bracelets
Week 3: (3 + 1 + 2 + 3 + 2 + 3 + 2) / 7 = 2.14 bracelets
Week 4: (9 + 7 + 8 + 8 + 11 + 6 + 7) / 7 = 8.71 bracelets
Based on these calculations, the mean number of bracelets sold is highest in Week 2 with 9.29 bracelets. Therefore, Week 2 would be the best estimate for the jewelry store's weekly sales throughout the year.
On a typical day, a jewelry store sells 8 bracelets. The data show the number of bracelets sold on each day for four weeks at a jewelry store.
Week 1: 7, 8, 7, 9, 1, 6, 8
Week 2: 6, 7, 8, 7, 9, 8, 17
Week 3: 3, 1, 2, 3, 2, 3, 2
Week 4: 9, 7, 8, 8, 11, 6, 7
For which week would the mean of the data be a good estimate of the jewelry store's weekly sales throughout the year?
