Question 1

The Highway Safety Department wants to study the driving habits of individuals. A sample of 41

cars traveling on the highway revealed an average speed of 60 miles per hour and a standard

deviation of 7 miles per hour. The population of car speeds is approximately normally distributed.

Determine a 90% confidence interval estimate for the speed of all cars.

1. A questionnaire about study habits was given to a random sample of students taking a large introductory statistics class. Students were asked if they studied most nights in a week: yes or no. The results are that the sample proportion of students who answered “yes” (?̂) was 0.4. Consider the same scenario as in Problem 1. a) Calculate a confidence interval for sample size n = 1000, ?̂= 0.4, and the following confidence levels: 80%, 90%, and 99%. You...
