youre amazing!! thank you for helping me in advance, i needed this (1 point) Justin is interested in buying a digital phone. He visited 13 stores at random and recorded the price of the particular phone he wants. The sample of prices had a mean of $184.07 and a standard deviation of $30.98. (a) What critical value re should be used for a 95% confidence interval for the mean, M.of the distribution? (b) Calculate a 95% confidence interval for the...
I just need answer for 1.b), thanks for helping me out! 1/4 3/4 1.a) Consider an agent who will live for two periods with utility function U(x1, x2) = xi'*x* . The agent receives incomes 11 and 12 in periods 1 and 2 respectively. If the market interest rate is r = 10% and I1 = $10 and I2 = $10, solve for the agent's optimal consumption in each period. Graph the budget constraint and some indifference curves. 1.b) Suppose...
