A group of parents examines a random sample of insurance bills in order to determine if there is evidence to suggest that the cost of auto insurance for teenage boys costs more, on average, than for teenage girls. The mean annual cost for 42 teenage boys was $619. For 37 teenage girls, it was $579. From past years, it is known that the population standard deviation for each group is $150. Does this data provide evidence at a significance level of alpha equals 0.05 that the mean cost for auto insurance for teenage boys is greater than that for teenage girls?

In order to determine the load capacity of a lift, a random
sample of 15lifts are stress tested and the maximum weight that
each life can bear before malfunctioning is recordedas the “Maximum
Load”. Suppose thatthe mean of the maximum load is1279 pounds and
the standard deviation of the maximum loadis 123 pounds.
a.Verify that the conditions for constructing confidence
intervals for the mean are met.
b.Compute and interpret a 99% confidence interval for the mean
of the maximum weight...

In a study of parents who have children with ADHD, a simple
random sample of parents were asked to rate their overall stress
level. A higher score indicates greater stress. The mean rating for
the 50 parents in the study was reported to be 46.8 with a standard
deviation of 10.34. The researchers considered a score greater than
45 to represent extreme stress. Is there evidence that the mean
stress level for the parents in this study is above this...

A pediatrician asked a random sample of parents to report how
long it took their toddler to fall asleep at night. Among 51
toddlers the mean time to fall asleep at night was 23.4 minutes
with a standard deviation of 6.7 minutes. Fill in the missing
values (rounded to one digit after the decimal point) to estimate
the parameter.
Using 95% confidence, the mean time to fall asleep among all
toddlers is between ______ and ______.

a) In order to determine the average price of hotel rooms in
Atlanta, a sample of 61 hotels were selected. It was determined
that the average price of the rooms in the sample was $111.9. The
population standard deviation is known to be $19. We would like to
test whether or not the average room price is significantly
different from $110.
Compute the test statistic.
