A random sample of 46 college students reported the number of hours per day they typically spend on social media. Their sample mean is, M = 2.61, and their standard deviation is, s = 1.02. What is the margin of error, (tci)(SEMs), for this data?
t critical value at 0.05 level with 45 df= 2.014
Margin of error = t * S / sqrt(n)
= 2.014 * 1.02 / sqrt(46)
= 0.3029

A random sample of 46 college students reported the number of hours per day they typically spend on social media. Their sample mean is, M = 2.61, and their standard deviation is, s = 1.02. What is the point estimate of the mean time spent per day on social media for the population of college students?
A random sample of 46 college students reported the number of hours per day they typically spend on social media. Their sample mean is, M = 2.61, and their standard deviation is, s = 1.02. If you plan to construct a 95% confidence interval for the population mean, what t critical value should you use based on this data?
A random sample of community college students was asked the number of hours they sleep on a typical week-night during a given academic term. The sample data are as follows: 8 6 4 5 3 7 S 4 3 4 4 5 6 8 7 7 7 3 3 4 What is the 90% confidence interval estimate for the true mean amount of sleep time per night spent by community college students during a academic term? a) The data give...
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...
A random sample of 51 college students shows that they spend, on average, 4.5 hours on video games every night, with a standard deviation of 1.25 hours. Construct a 98% confidence interval to estimate the mean number of hours that college students spend on video games every nigh

A recent research study reported that Americans spend an average of 3.6 hours on social media - per person per day. If the standard deviation for the number of hours of social media per day is 3 and a random sample of 145 Americans is selected for further study, answer the following questions about the sampling distribution: 1) The mean of this sample of n=145 belongs to a sampling distribution. What is the shape of this sampling distribution? 2) What...
