A researcher is interested in finding a 98% confidence interval for the mean number minutes students are concentrating on their professor during a one hour statistics lecture. The study included 135 students who averaged 42.1 minutes concentrating on their professor during the hour lecture. The standard deviation was 11.6 minutes. Round answers to 3 decimal places where possible. a. To compute the confidence interval use a ? O distribution.

Transcribed Image Text:A researcher is interested in finding a 98% confidence interval for the mean number minutes
students are concentrating on their professor during a one hour statistics lecture. The study
included 135 students who averaged 42.1 minutes concentrating on their professor during
the hour lecture. The standard deviation was 11.6 minutes. Round answers to 3 decimal
places where possible.
a. To compute the confidence interval use a
distribution.
b. With 98% confidence the population mean minutes of concentration is between
and
minutes.
c. If many groups of 135 randomly selected members are studied, then a different confidence
interval would be produced from each group. About|
percent of these confidence
intervals will contain the true population mean minutes of concentration and about
percent will not contain the true population mean minutes of concentration.
