A researcher is interested in finding a 90% confidence interval for the mean number minutes students are concentrating on their professor during a one hour statistics lecture. The study included 117 students who averaged 40.9 minutes concentrating on their professor during the hour lecture. The standard deviation was 11.8 minutes. Round answers to 3 decimal places where possible. a. To compute the confidence interval use a ?v distribution. b. With 90% confidence the population mean minutes of concentration is between and minutes. c. If many groups of 117 randomly selected members are studied, then a different confidence percent of these confidence interval would be produced from each group. About intervals will contain the true population mean minutes of concentration and about percent will not contain the true population mean minutes of concentration.

Suppose that textbook weights are normally distributed. You measure 33 textbooks' weights, and find they have a mean weight of 61 ounces. Assume the population standard deviation is 13.2 ounces. Based on this, construct a 90% confidence interval for the true population mean textbook weight. Round answers to 2 decimal places.
In a survey, 373 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $36.85 and standard deviation of $19.05. Estimate how much a typical parent would spend on their child's birthday gift (use a z-interval at a 80% confidence level). Give your answers to 2 decimal places. Express your answer in the format of E. $ + $
The distribution of study times for first-year students follow a Normal distribution with a standard deviation σ = 48 minutes. Suppose a sample of 344 students found that the mean study time for these students was x¯= 170 minutes per week. Use this to find a 94.38% confidence interval to estimate the mean study time for all students. We are 94.38% confident that the mean study time for first-year students is between the following ( answer) minutes and ( answer) minutes. The answer needs to be the mean study time for first-year students is between what amount of minutes and the following minutes.
