enter your answers in the boxes.
round to the nearest tenth.
the population mean is
hours.
the sample mean is
hours.

The Sample Mean of hours slept of the ten men asked is 8.4 hours.

The population Mean of hours slept of all the members of the theater group is 8.3 hours.

Step-by-step explanation:

Given is the table shows the number of hours of sleep all members of a theater group got the night before their musical.

8 8.5 8 7.5 9 9

8 7 7 9 8 8

8 7 7 8 7.5 8.5

7.5 8 8.5 9 8 7.5

Total all these entries and divide by 20 to get population mean.

Sum = 50+47+46+48.5=191.5

Population mean = 191.5/24 =7.98

Sample size is 10

Sum =84

Sample mean =8.4

the answer is y = 11.54

hope this : )
