1. For the following exercise, complete the following: Find the mean, median, and range for each of the two data sets. Find the standard deviation using the rule of thumb for each of the data sets. Compare the two sets and describe what you discover. The following data...

Use this information to construct the 90% and 95% confidence intervals for the population mean. Which interval is wider? If convenient, use technology to construct the confidence intervals. A random sample of 33 gas grills has a mean price of $648.70 and a standard deviation of $57.50.

A box contains five pennies, three dimes, one quarter, and one half-dollar. Construct a probability distribution and draw a graph for the data.

The distribution of a sample means is not always a normal distribution. Under what circumstances will the distribution of sample means not be normal

FICO Credit Scores data set 24 appendix B includes a simple random of FICO credit rating scores. As of this writing, the mean FICO score was reported to be 678. Use a 0.05 signficance level to test the claim that the sample of FICO scores comes from a population with a mean equal to 678.

Using the confidence interval when conducting a two-tail test for the population mean (m) we do not reject the null hypothesis if the hypothesized value for mu: Answer is to the left of the lower confidence limit (LCL) is to the right of the upper confidence limit (UCL)...
