Question

According to the South Dakota Department of Health, the number of hours of TV viewing per week is higher among adult women than adult men. A recent study showed women spent an average of 32 hours per week watching TV, and men, 24 hours per week. Assume that the distribution of hours watched follows the normal distribution for both groups, and that the standard deviation among the women is 5.0 hours and is 5.3 hours for the men. What percent of the women watch TV less than 36 hours per week?

Answer 1

Answer:

The percentage fo women who watch tv less than 36 hours per week is 80%

Explanation:

The mean, μ= 36

The standard deviation, σ= 5.0

The percent of the women, who watch tv less than 36 hours per week:

P(x ≤ 36)= P (z ≤ 36-32÷ 5.0)

= P( z≤ 0.8)

= 0.8

= 80%
