4. The bad debt ratio for a financial institution is defined to be the dollar value of loans defaulted divided by the total dollar value of all loans made. Suppose that a random sample of seven Ohio banks is selected and the bad debt ratios for are calculated. The mean is 6 percent and s is 1.826 percent. Banking officials claim that the mean bad debt ratio for all Midwestern banks is 3.5 percent and that the mean bad debt ratio for Ohio banks is higher. Assuming that bad debt ratios for Ohio hanks are approximately normally distributed, use critical values and the given sample information to test the hypotheses by setting alpha equal to 0.01.

Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.

Question

4. The bad debt ratio for a financial institution is defined to be the dollar value of loans defaulted divided
by the total dollar value of all loans made. Suppose that a random sample of seven Ohio banks is selected
and the bad debt ratios for are calculated. The mean is 6 percent and s is 1.826 percent. Banking officials
claim that the mean bad debt ratio for all Midwestern banks is 3.5 percent and that the mean bad debt ratio
for Ohio banks is higher. Assuming that bad debt ratios for Ohio hanks are approximately normally
distributed, use critical values and the given sample information to test the hypotheses by setting alpha
equal to 0.01.

5. Budget lapsing occurs when unspent funds do not carry over from one budgeting period to the next. Because budget lapsing often leads to a spike in expenditures at the end of the fiscal year, the researchers recorded expenses per full-time equivalent employee for each in a sample of 1,751 army hospitals. The sample yielded the following summary statistics: x $6,563 and s $2,484. Estimate the mean expenses for full-time equivalent employee of all US army hospitals using a 90% confidence interval. Interpret the result.

In a study comparing banks in two countries, a sample of 142 matched pairs of banks was formed. Each pair contained one bank from country x and one from country y. The pairings were made in such a way that the two members were as similar as possible in regard to such factors as size and age. The ratio of total loans outstanding to total assets was calculated for each of the banks. For this ratio, the sample mean difference (country x - country y) was 0.0579, and the sample standard deviation of the differences was 0.3086.

13. Dave likes to grow cucumbers, and each year he experiments with ways to improve his crop. This summer, he wants to determine whether the new fertilizer he has seen advertised will increase the mean number of cucumbers produced per plant. He uses the old fertilizer on 15 cucumber plants and the new fertilizer on the other 13 plants. Over the course of the growing season, he calculates a mean of 17.4 cucumbers per plant for the old fertilizer, with a standard deviation of 2.0 cucumbers. He calculates a mean of 21.6 cucumbers per plant for the new fertilizer, with a standard deviation of 2.7 cucumbers. You may assume that both samples came from populations that are approximately normal. Assume that the population variances are not equal. a. Determine the best point estimate for the true mean difference in cucumber production. Correct notation counts. b. Construct a 95% confidence interval for the true mean difference in cucumber production. For credit, your work must include a…
