Researchers doing a study comparing time spent on social media and time spent on studying randomly sampled 200 students at a major university. They found that students in the sample spent an average of 2.3 hours per day on social media and an average of 1.8 hours per day on studying. If all the students at the university in fact spent 2.2 hours per day on studying, with a standard deviation of 2 hours, the shape of the sampling distribution...

Are the grades one receives in a course related to the amount of
time spent studying the subject? To analyze this possibility, a
student took a random sample of 60 students who had enrolled in an
accounting class last semester. She asked each student to report
his or her grade in the course and the total number of hours spent
studying accounting. The data are stored in this Excel file (SEE

from prior experience we know time spent studying for an exam is approximately normally distributed.You survey HC students and ask the participating students how many times do they spend studying for the exam. From your sample of 36 HC students ,you obtained the mean time spent to study for an exam was 160 minutes,with standard deviation of 40 mins. 2)construct a 95% confidence interval for the mean study time (in minutes) of HC students.

11. A Biology instructor is wondering about the average amount of time a student spent studying for a test. She asks a random sample of 18 of her students for their amount of study time and determines that the mean study time in the sample is 6.3 hours with a standard deviation in the sample of 1.94 hours. She believes that it is reasonable to assume that the overall distribution of study times is normal. Give this instructor a 98%...
