) According to a certain survey, adults spend
2.252.25
hours per day watching television on a weekday. Assume that the standard deviation for "time spent watching television on a weekday" is
1.931.93
hours. If a random sample of
6060
adults is obtained, describe the sampling distribution of
x overbarx,
the mean amount of time spent watching television on a weekday.
x overbarx
is approximately normal
with mu Subscript x overbarμxequals=
2.25
and
sigma Subscript x overbarσxequals=0.2491620.249162 .
(Round to six decimal places as needed.)
(c) Determine the probability that a random sample of
6060
adults results in a mean time watching television on a weekday of between 2 and 3 hours.
