Use the confidence interval to find the margin of error and the sample mean. russellc, September 12, 2018September 14, 2018, Statistics, 0 (0.264,0.460) The margin of error is 0.098.The sample mean is .3620.

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Upper H 0 when the level of significance is (a) alpha equals 0.01, (b) alpha equals 0.05, and (c) alpha equals 0.10. russellc, September 19, 2018September 19, 2018, Statistics, 0 see excel spreadsheet.

You are given the sample mean and the population standard deviation. Use this information to construct the 90% and 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. If convenient, use technology to construct the confidence intervals. A random sample of 60 home theater systems has a mean price of $140. Assume the population standard deviation is $15.40 Construct a 90% confidence interval for the population mean. The 90% confidence interval is (nothing,nothing). russellc, September 12, 2018September 14, 2018, Statistics, 0
