We are interested in estimating the amount of time students at UAlbany spend weekly using Instagram. A sample of 50 students produce the following samples: 20 20 20 0 1 8.5 15 28 7 24 0.58 7 4.2 0 18 2.5 2 0 3 1.18 72 0.58 0 7.5 2.5 0.25 8 9 0 1.183 1 0 12 1 4 3 0 0 3 35 12 6 3.5 5 10 6 0 26 0 0 Note: You can cut and past these numbers into an excel spreadsheet to help you calculate the mean and the standard deviation and compute the confidence interval. If you have trouble pasting them, paste them to a text file first and then copy from there. Find a 95% confidence interval for the true mean time UAlbany students spend weekly using Instagram: The sample mean is: (Round answer to 4 decimals.) The sample standard deviation is: (Round answer to 4 decimals.) The 95% confidence interval is ( , ). (Round answers to 2 decimals.)
