Meg concludes that students spend a mean of 7 hours in school each day. Tara thinks the mean is 6 hours. Who is correct—Meg or Tara? Explain your answer in two or three sentences. Make sure to use facts to support your answer.

The mean time spent in school is approximately 6 hours each day and Tara is correct

Step-by-step explanation:

The given data is presented here as follows;

Number of hours in school per day,      4,        5,        6,        7,         8

Sample A:,                                               70       100    125      135       70

Sample B:,                                               80        90     120     125      85

For sample A, we have;

The total number of hours spent by sample A = 4 × 70 + 5 × 100 + 6 × 125 + 7 ×135 + 8 ×70 = 3035 hours

The number of students in sample A = 70 + 100 + 125 + 135 + 70 = 500

The mean number of hours spent in school by sample A = 3035 /500 = 6.07

For sample B, we have;

The total number of hours spent by sample A = 4 × 80 + 5 × 90 + 6 × 120 + 7 ×125 + 8 ×85 = 3045 hours

The number of students in sample A = 80 + 90 + 120 + 125 + 85 = 500

The mean number of hours spent in school by sample A = 3045 /500 = 6.09

The cumulative data, we have;

(3035 + 3045)/1000 = 6.08

Therefore, the mean is approximately 6 hours each day and Tara is correct.
