The Florida Individual Giving Survey (November 2019), administered by the Florida Nonprofit Alliance and the Florida Department of Agriculture and Consumer Services, compiled information on annual charitable giving amounts for a sample of approximately 3,000 Florida residents. The number of these Florida-resident givers in each of 5 donation amount categories (saved in the accompanying file) is shown in the table.

a. If the true proportions of charitable givers in each donation amount group are the same, how many of the 3,000 sampled givers would you expect to find in each category?

b. Give the null hypothesis for testing whether the true proportions of Florida charitable givers in each donation amount group are the same.

c. Compute the chi-square test statistic for testing the null hypothesis, part b.

d. Find the rejection region for the test if α = .10.

e. Give the appropriate conclusion for the test in the words of the problem.
