On January 30th, 2018, Dr. Ziegler took a random sample of STAT 104 students.1 Students were asked how many Facebook friends they had. Out of 30 respondents who had Facebook accounts, the mean number of friends was 589.10 with a standard error of 72.98.

Describe the parameter of interest in context.
What is the 95% confidence interval?
Interpret the 95% confidence interval.
Is 500 friends a plausible value for the population of all STAT 104 students on January 30th, 2018? Explain.
Is 750 friends a plausible value for the population of all STAT 104 students on January 30th, 2018? Explain.

A random sample of 13 students were asked how long it took them to complete a certain exam. The mean length of time was 105.6 minutes, with a standard deviation of 71.7 minutes. Find the lower bound of the 90% confidence interval for the true mean length of time it would take for all students to complete the exam. Round to one decimal place (for example: 108.1)

10) A random sample of 13 students were asked how long it took them to complete a certain exam. The mean length of time was 120.1 minutes, with a standard deviation of 84.0 minutes. Find the lower bound of the 90% confidence interval for the true mean length of time it would take for all students to complete the exam. Round to one decimal place (for example: 108.1). Write only a number as your answer. Do not write any units....

A simple random sample of 70 Stat 20 students is taken from my class of 340 students; the average number of units these students is taking is 16.1, with an SD of 1.9. Last spring I taught a smaller class with only 96 students, and those 96 students took an average number of units of 15.5, with an SD of 2.2. Do a hypothesis test to decide whether the average number of units for this semester's Stat 20 class is...

In a study, 38 random students of a sample 1 were shown positive evaluations of an instructor and 33 random students of sample 2 were shown negative evaluations of the instructor. Then all subjects were shown the same lecture video given by the instructor. Sample 1 gave a mean rating of 6.6 with a standard deviation of 0.75, while sample 2 gave a mean rating of 5.9 with a standard deviation of 1. Perform a hypothesis test at the 0.06...

USING R : A random sample of 40 students took an SAT preparation course prior to taking the SAT. The sample mean of their quantitative SAT scores was 560 with a s.d. of 95, and the sample mean of their verbal SAT scores was 525 with a s.d. of 100. Suppose the mean scores for all students who took the SAT at that time was 535 for the quantitative and 512 for the verbal. Do the means for students who...

. A researcher took a random sample of 600 college students and surveyed them about how many days of class they missed per semester. On average, the sample missed 3.1 days of class. If the sample standard deviation is .45, construct a confidence interval to estimate the true population mean at the 95% confidence level (.05 alpha level). Make sure to interpret your results in a sentence or two! (HINT: Make sure you use the correct formula for this question,...

In a study, 38 random students of sample 1 were shown positive evaluations of an instructor and 33 random students of sample 2 were shown negative evaluations of the instructor. Then all subjects were shown the same lecture video given by the instructor. They were then asked to rate the instructor out of 10, with 10 being the highest. Sample 1 gave a mean rating of 6.6 with a standard deviation of 0.75, while sample 2 gave a mean rating...
