Question

a. Set up the hypotheses to test whether the mean profitability differs between condominiums and apartment buildings. H0: μ1 = μ2 (The mean profitability of condominiums is equal to the mean profitability of apartment buildings) Ha: μ1 ≠ μ2 (The mean profitability of condominiums is not equal to the mean profitability of apartment buildings) b-1. Calculate the value of the test statistic. t = (x̄1 - x̄2) / √((s1^2/n1) + (s2^2/n2)) Where: x̄1 = $243,900 (mean profitability for condominiums) x̄2 = $236,700 (mean profitability for apartment buildings) s1 = $22,300 (standard deviation for condominiums) s2 = $20,000 (standard deviation for apartment buildings) n1 = n2 = 31 (sample size for both condominiums and apartment buildings) Calculate the test statistic using the given values.

          a. Set up the hypotheses to test whether the mean profitability differs between condominiums and apartment buildings.

H0: μ1 = μ2 (The mean profitability of condominiums is equal to the mean profitability of apartment buildings)
Ha: μ1 ≠ μ2 (The mean profitability of condominiums is not equal to the mean profitability of apartment buildings)

b-1. Calculate the value of the test statistic.

t = (x̄1 - x̄2) / √((s1^2/n1) + (s2^2/n2))

Where:
x̄1 = $243,900 (mean profitability for condominiums)
x̄2 = $236,700 (mean profitability for apartment buildings)
s1 = $22,300 (standard deviation for condominiums)
s2 = $20,000 (standard deviation for apartment buildings)
n1 = n2 = 31 (sample size for both condominiums and apartment buildings)

Calculate the test statistic using the given values.
