ROUND ALL CALCULATIONS TO TWO (2) DECIMAL PLACES a. (15 pts) Please draw the Keynesian Cross assuming the following information. Be sure to specify at what point consumption and disposable income are equal. Marginal Propensity to Consume = .88 Autonomous Consumption = $525 b. (5 pts) Assume that your disposable income is $760. How much are you consuming? Are you saving or dissaving? c. (10 pts) Assume that autonomous consumption increases to $890. Please illustrate this change on graph from part a. Again, you must specify at what point consumption and disposable income are equal. d. (5 pts) Based on the change in part c, illustrate what will happen to aggregate demand.

Expert Solution
In this question I firstly make consumption function, which include autonomous consumption and consumption from disposable income. Aggregate demand is the function of consumption by household, expenditure on investment by enterprenuer and government expenditure. As other this are not given in question so assumed to be zero.
Then for equilibrium put AD equals to Y(output). As AD is equal to total consumption so at equilibrium consumption is equal to disposable income.
In part(b) there were given disposable income so he only consume .88 part of the disposable income remaining part he saves.

A machine that is programmed to package 2.05 pounds of cereal in
each cereal box is being tested for its accuracy. In a sample of 26
cereal boxes, the mean and standard deviation are calculated as
2.08 pounds and 0.14 pound, respectively. Use Table 2.

(Round all intermediate calculations to at least 4 decimal

small car traveling at 75 miles per hour equals 120 feet. A
transportation researcher wants to determine if the statement made
in the advertisement is false. She randomly test drives 36 small
cars at 120 miles per hour and records the braking distance. The
sample average braking distance is computed as 111 feet. Assume
that the population standard deviation is...

(The Boston Globe, August 16, 2010). You collect the
following sample data to verify the results of the report. You also
use the historical (population) standard deviation of 8.2 years for
females and 8.6 years for males. (You may find it useful to
