Jocelyn believes that the amount of sleep she tends to
get on weekends differs from the amount of sleep she
tends to get during the school week. To investigate this
claim, she randomly selects 10 weekend days and 10
school days. She consults her smart watch to
determine the number of hours she slept for each of the
selected days. Here are the data.
School week: 7, 7.5, 8, 6.5, 8, 7.5, 7, 6.5, 7, 8
Weekend: 9.5, 9.5, 8.25, 8.5, 7.5, 10.25, 8, 7, 9.5, 10
Jocelyn would like to determine if these data provide
convincing evidence that the true mean amount of
sleep she gets on the weekend differs from the true
mean amount of sleep she gets during the school
week. Let w the true mean amount of sleep Jocelyn
gets on the weekend and us the true mean amount of
sleep she gets during the school week. Are the
conditions for inference met?
O No, the random condition is not met.
O
No, the 10% condition is not met.
O
No, the Normal/large sample condition is not met
Yes, all of the conditions for inference have been
met.
