Each person in a random sample of 222 male teenagers
and a random sample of 307 female teenagers was asked how
many hours he or she spent online in a typical week. The sample
mean and standard deviation were 15.3 hours
and 11.2 hours for males
and 14.1 and 11.8 for females. (Use a
statistical computer package to calculate
the P-value.
Use 𝜇males − 𝜇females. Round
your test statistic to two decimal places, your df down to the
nearest whole number, and your P-value to three
decimal places.)
