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 40 hours per week watching tv, and men, 34 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 4.7 hours and is 5.2 hours for the men.

a.
what percent of the women watch tv less than 43 hours per week? (round z-score computation to 2 decimal places and your final answer to 4 decimal places.)

probability
b.
what percent of the men watch tv more than 30 hours per week? (round z-score computation to 2 decimal places and your final answer to 4 decimal places.)

a) 73.84%, b) 77.64%.

Step-by-step explanation:

Since we have given that

Average number of hours women spent per week watching TV = 40

Standard deviation =4.7 hours

Average number of hours men spent per week watching TV = 34

Standard deviation = 5.2 hours

a.  What percent of the women watch TV less than 43 hours per week? (Round z-score computation to 2 decimal places and your final answer to 4 decimal places.)

So, X is less than 43 hours.

So, we get that

b. ) What percent of the men watch TV more than 30 hours per week? (Round z-score computation to 2 decimal places and your final answer to 4 decimal places.)

Since Y is more than 30 hours per week

So, it becomes

Hence, a) 73.84%, b) 77.64%.

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
