Do teachers find their work rewarding and satisfying? An article reports the results of a survey of 397 elementary school teachers and 261 high school teachers. Of the elementary school teachers, 223 said they were very satisfied with their jobs, whereas 121 of the high school teachers were very satisfied with their work. Estimate the difference between the proportion of all elementary school teachers who are satisfied and all high school teachers who are satisfied by calculating a 95% CI. (Use pelementary − phigh school. Round your answers to four decimal places.)

An article presents results of a survey of adults with diabetes.
The average body mass index (BMI) in a sample of 15 men was 30.4,
with a standard deviation of 0.6. The average BMI in a sample of 19
women was 31.1 with a standard deviation of 0.2. Assuming BMI is
normally distributed, find a 95% confidence bound for the
difference in mean BMI between men and women with diabetes. Be sure
to interpret the interval in context.

owning a cell phone. Use this information to construct a 90%
confidence interval estimate of the proportion of all Americans age
8 to 18 who own a cell phone. (Round your answers to three decimal
