The times that college students spend studying per week have a distribution skewed to the right with a mean of 8.6 hours and a standard deviation of 2.8 hours. Find the probability that the mean time spent studying per week for a random sample of 49 college students would be between 8.2 and 8.9 hours. Round your answer to two decimal places.

A sample of 200 college students are asked about how much time they spend studying for classes each week. The results show that the sample has a mean of 15 hours with a standard deviation of 5 hours. Explain these findings for someone who has never taken a statistics class before. Note that your job is to interpret the findings, NOT to explain how they were calculated! (10 points)

A claim is made that college students spend an average of 20 hours per week studying for their courses. You believe the true population average is different than 20 hours, and you would like to test the null hypothesis that μ = 20 hours versus the alternative hypothesis that μ ≠ 20 hours. You gather data from a random sample of 100 college students and calculate a test statistic of 1.2. This means the p-value would be what? A 0.0576...

1. To determine the average number of hours spent studying by college students per week, a sample of 39 students was randomly selected, and found to spend an average of 17.1 hours per week, with a standard deviation of 4.3 hours. Find the 90% confidence interval for the mean number of hours spent studying per week by all college students. What is the upper and lower bound? 2. If I asked a random student how many hours they study per...

An educational research group wants to know how many hours college students spend studying outside of class per week. If they survey 100 students and find an average 10.5 hours of studying a week, with a standard deviation of 2.25, find a 98% confidence interval for the true average number of hours spent studying. Answer choices: 10.5±.324 10.5±.225 None of these 10.5±.482 10.5±.524
