Use the one-proportion z-interval procedure to find the required confidence interval. A researcher wishes to estimate the proportion of adults in the city of Darby who are vegetarian. In a random sample of 1323 adults from this city, the proportion that are vegetarian is 0.068. Find a 90% confidence interval for the proportion of all adults in the city of Darby that are vegetarians.

A two proportion z interval was constructed for the difference in the two population proportions, p1- p2. The resulting 99% confidence interval was (–0.004, 0.12). A conclusion that could be drawn is: A: There is no significant difference between p1 and p2. B: There is a significant difference between p1 and p2. C: The range of possible differences between the two proportions could be from a 0.4% difference with p2 being larger up to a 12% difference with p1 being...

The following question can be answered in R code (using R-Studio or a program of your choice). Load the “star” data from the “faraway” package, and model “temp” using “light”. One may also suspect that the residuals (use all the data) follow a t distribution instead of normal. Using the same logic that we produced the QQ plot for comparing to the normal distribution, produce a QQ plot for comparing to a t distribution. You need to decide the degrees...
