The average number of hours slept per week for college seniors is believed to be about 60 hours. A researcher asks 10 random seniors at Florida Atlantic University how many hours they sleep per week. Based on the following results, should the researcher conclude that college seniors do or do not sleep an average of 60 hours per week?
Data (average number of hours slept per week): 70; 45; 55; 60; 65; 55; 55; 60; 50; 55

The University College is interested in the average number of hours per week that freshmen spend going to parties. They took a random sample of 300 freshmen and calculated a mean of 6 hours a week going to parties and a 95% confidence interval for the population mean to be 4 to 8 hours a week. Based on this information, what was their standard error of the mean?

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...

A scientific study was conducted to determine the hours of sleep that college students get per night. The college students surveyed slept an average of 7.8 hours per night. The margin of error of the survey was 0.5 hours. Construct a confidence interval for the average hours of sleep per night that college students get.

The belief is that the mean number of hours per week of part-time work of high school seniors in a city is 10.5 hours. Data from a simple random sample of 23 high school seniors indicated that their mean number of part-time work was 11.5 with a standard deviation of 1.4. Test whether these data cast doubt on the current belief. (use α = 0.05) Part d: Determine the P-value for your test. a) p-value = 0.997581 b) p-value =...

A recent study found out that college students average about 7 hours of sleep per night. However, researchers at an urban college in a big city are interested in showing that their students sleep less than 7 hours on the average. The researchers conducted a simple random sample of n=100 students on campus. They found out that the students averaged 6.6 hours. The previous studies showed that the population standard deviation (s) of the nightly sleeps was...

Some college graduates employed full-time work more than 40 hours per week, and some work fewer than 40 hours per week. We suspect that the mean number of hours worked per week by college graduates, , is different from 40 hours and wish to do a statistical test. We select a random sample of college graduates employed full-time and find that the mean of the sample is 36 hours and that the standard deviation is 3 hours. Based on this...

A graduate student believed that, on the average, college students spend more time on the Internet compared to the rest of the population. She conducted a study to determine if her hypothesis was correct. The student randomly surveyed 25 students and found that the average amount of time spent on the Internet was 8.75 hours per week with a SD = 3 hours. The last census found that, on the average, people spent 11 hour per week on the Internet....
