Professor York randomly surveyed 240 of the 4937 students at Oxnard University and found that 150 of the students surveyed watch more than 10 hours of television weekly. Develop a 95 percent confidence interval to estimate the total number of students who watch more than 10 hours of television each week. The upper bound of this confidence interval rounded to the nearest student is:

An economics professor is interested in seeing if the mean hours worked by students in a week at part time or full time jobs (including work study) is greater than 10. To accomplish this, the professor randomly selected 240 students from the university. It was found that the distribution was right skewed and unimodal. The mean was 8 hours with a standard deviation of 4. The professor then did a hypothesis test. Please find the test statistic for this hypothesis...

A statistics professor asked her students whether or not they were registered to vote. In a sample of 52 of her students (randomly sampled from 700 students), 34 said they were registered to vote. 1. Find a 95% confidence interval for the true proportion of the professor's students who were registered to vote. (Make sure to check any necessary conditions and to state a conclusion in the context of the problem.) 2. A reader of the results concludes that "I...

A professor at a university wants to estimate the average number of hours of sleep students get during exam week. On the first day of exams, she asked 21 students how many hours they had slept the night before. The average of the sample was 4.72 with a standard deviation of 1.58. When estimating the average amount of sleep with a 90% confidence interval, what is the margin of error? Question 3 options: 1) 0.5947 2) 0.5933 3) 0.3448 4)...
