The company sells both through mail order and via the internet. Random samples of sales receipts were studied for mail order sales and internet sales, with the total purchase being recorded for each sale. A random sample of 7 sales receipts for mail order sales results in a mean sale amount of $81.10 with a standard deviation of $23.25. A random sample of 15 sales receipts for internet sales results in a mean sale amount of $64.30 with a standard deviation of $28.25. Using this data, find the 90 % confidence interval for the true mean difference between the mean amount of mail order purchases and the mean amount of internet purchases. Assume that the population variances are not equal and that the two populations are normally distributed. Step 1 of 3: Find the critical value that should be used in constructing the confidence interval.

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.

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.
