Problem 3 (2 points): Consider the macroeconomic model defined by National income: Y = C + I + G* (G* > 0)
Consumption: C = aY + b (0 < a < 1, b > 0)
Investment: I = cr + d (c < 0, d > 0)
Money supply: MS* = k1Y + k2r (k1> 0, k2< 0, MS* > 0)
Show that this system can be written as Ax = b, where

a/ Use Cramer’s rule to find C;
b/ Then write down the money supply multiplier for C and deduce its meaning

Atextile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. the company wishes to test the hypothesis upper h subscript 0 baseline colon mu equals 12 against upper h subscript 1 baseline colon mu less-than 12 using a random sample of n equals 4 specimens. calculate the p-value if the observed statistic is x overbar equals 11.8. round your final answer to five decimal places (e.g. 98.76543).
