This informatio lected by the Hawaii Department of Business Economic Development and Tourism, is used to allocate state funds for many social services. Va. Use KStat or Excel to calculate the sample mean and standard deviation for each county. b. Set up hypothesis tests to determine if a statistically significant differ- ence exists between each pair of counties. You will need to set up six separate tests. c. Use the formulas from Section 2.5 to calculate the test statistic for each of d. Use the test statistics from part c to compute p-values for each of the e. Repeat the p-value calculations for each test directly using Excel's TTEST the six tests. six tests. function. Ensure your answers resemble the ones you found in part d. Some rounding in the hand calculations will give you slightly different answers. See http://www2.hawaii.gov/DBEDT/ 05
