Part 1

1. What is the sample mean?
2. What is the sample standard deviation?
3. What is the sample size?
4. Can you assume normality to use the normal distribution? Explain why.
5. Calculate a 95% confidence interval estimate of the population mean from this sample.
6. Interpret your interval estimate.
7. A Banking Industry report came out saying most banks averaged less than $55,000 in their loans made last year. Is Society Bank "most banks?" Explain using your confidence interval.
8. Use the reported average loan amount of $55,000 by the banking industry to test to see if Society Bank loans are higher on average than the industry as a whole. Use =0.05
   • State the claim, counterclaim, and hypotheses. Remember, you are ALWAYS testing the null (H0) hypothesis but there are rules governing the formation of the null and alternative hypotheses. Rejection of the null means acceptance of the alternate, Failing to reject the null = failing to accept the alternate. Failing to reject the null DOES NOT MEAN Rejecting or Accepting the alternate.
   • Hypothesis test the population mean (e.g. use the appropriate Excel Calculator). If you use tools such as the Excel calculator, save your file(s) and upload it/them with your report.
   • Write conclusions including your p-value, test statistic, and level of significance.

Part 2

1. What proportion of loans are real estate loans?
2. Calculate a 95% confidence interval for the proportion of loans which are real estate loans. Show your work. If you use the Excel calculator, save it, and attach it to your submitted work. Be sure to interpret you interval estimate.
3. A Banking Industry report claimed at least 50% of loans are commercial loans. Test this claim at a level of 0.05 (=0.05). Are commercial loans less than half of all loans?
   • State the hypotheses. You need null and alternative hypotheses.
   • Hypothesis test the population proportion (e.g. use the appropriate Excel Calculator). If you use tools such as the Excel calculator, save your file(s) and upload it/them with your report.
   • Write conclusions including your p-value, test statistic, and level of significance
