Student learning outcomes
The student will select the appropriate distributions to use in each case.
The student will conduct hypothesis tests and interpret the results.
Television survey
In a recent survey, it was stated that Americans watch television on average four hours per day. Assume that
σ = 2. Using your class as the sample, conduct a hypothesis test to determine if the average for students at your school is lower.
H
0 : _____________
H
a : _____________
In words, define the random variable. __________ = ______________________
The distribution to use for the test is _______________________.
Determine the test statistic using your data.
Draw a graph and label it appropriately.Shade the actual level of significance.
Graph:
Determine the
p -value.
Do you or do you not reject the null hypothesis? Why?
Write a clear conclusion using a complete sentence.
Language survey
About 42.3% of Californians and 19.6% of all Americans over age five speak a language other than English at home. Using your class as the sample, conduct a hypothesis test to determine if the percent of the students at your school who speak a language other than English at home is different from 42.3%.

Jeans survey
Suppose that young adults own an average of three pairs of jeans. Survey eight people from your class to determine if the average is higher than three. Assume the population is normal.

is it possible to leave every good at the same level
Joseph
I don't think so. because check it, if the demand for chicken increases, people will no longer consume fish like they used to causing a fall in the demand for fish

is not really possible to let the value of a goods to be same at the same time.....

Suppose the inflation rate is 6%, does it mean that all the goods you purchase will cost
6% more than previous year? Provide with reasoning.
Not necessarily. To measure the inflation rate economists normally use an averaged price index of a basket of certain goods. So if you purchase goods included in the basket, you will notice that you pay 6% more, otherwise not necessarily.
Good day
How do I calculate this question: C= 100+5yd G= 2000 T= 2000 I(planned)=200.
Suppose the actual output is 3000. What is the level of planned expenditures at this level of output?

I want to know how can we define macroeconomics in one line
Muhammad
it must be .9 or 0.9
no Mpc is greater than 1
Y=100+.9Y+50
Y-.9Y=150
0.1Y/0.1=150/0.1
Y=1500

hi can someone help me on this question
If a negative shocks shifts the IS curve to the left, what type of policy do you suggest so as to stabilize the level of output?
discuss your answer using appropriate graph.
