Adults tend to believe that a majority of teenagers sleep in on Saturdays, but maybe that is a misconception. A
random sample of 120 teenagers showed that 48 slept in the previous Saturday. Use the computer output provided
below to determine if there is convincing evidence at the a= 0.05 level that the true proportion of teenagers who
slept in on the previous Saturday is less than 0.5.
Use this computer output to answer the questions.
Based upon the 95% confidence interval, it is reasonable to claim that the true proportion of all teenagers who slept
in on the previous Saturday is between which two values?
O 0.3124 and 0.6876
O 0.3124 and 0.4877
O 0.4877 and 0.6876
O 0.5123 and 0.6876
