ElenaW [278]

From the question we are told that:

Total Sample size n=500

Dan's mean \=x_D= 3hr

Bret's mean \=x_D= 4hr

Generally, the  Total hours spent doing leisure and sports activities  is mathematically given by

For Sample A

T_a=(1*70)+(2*90)+(3*135)+(4*140)+(5*65)\\\\

T_a=1540 hours

For Sample B

T_b=(1*80)+(2*80)+(3*130)+(4*135)+(5*75)

T_b=1545

Therefore

Average Time spent doing leisure and sports activities by an American Adult

For Sample A

T_A=\frac{T_a}{n}

T_A=\frac{1540}{500}

T_A=3.08

T_A \approx 3

For Sample B

T_A'=\frac{T_b}{n}

T_A'=\frac{1545}{500}

T_A'=3.09

T_A' \approx 3

Therefore

Dan is Correct because 3.08 or 3.09 is approximately equal to 3
