An advertising executive claims that there is a difference in the mean household income for credit cardholders of Visa Gold and of MasterCard Gold. A random survey of
16 Visa Gold cardholders resulted in a mean household income of $75,650 with a standard deviation of $11,400. A random survey of 7 MasterCard Gold cardholders
resulted in a mean household income of $68,280 with a standard deviation of $10,900. Is there enough evidence to support the executive's claim? Let μ₁ be the true
mean household income for Visa Gold cardholders and μ2₂ be the true mean household income for MasterCard Gold cardholders. Use a significance level of a = 0.2
for the test. Assume that the population variances are not equal and that the two populations are normally distributed.
Step 3 of 4: Determine the decision rule for rejecting the null hypothesis Ho. Round your answer to three decimal places.

Let the IS equation be Y = (1b) is the marginal propensity to save, g is the investment sensitivity to interest rates, and A is an aggregate of exogenous variables. Let the LM equation be Y = +=R, where k and 1 are income and interest sensitivity of money demand, and Mo is real money balances. Mo k k It is given b = 0.7, g = 100, A = 252, k = 0.25, l = 200, and Mo 176. a) Utilize the given numbers to substitute the variables in the model, and then write down the IS-LM equation system in matrices form. b) Solve for the equilibrium values of Y and R using Cramer's Rule.

Which firm (1 or 2) is considered an ‘uncomfortable' workplace? c) What is the CWD for the firm considered an ‘uncomfortable' workplace when it wants to hire employee number 10? d) Two industries require workers with the same characteristics (skills and experience).
