Grades and AM/PM Section of Stats: There were two large sections of statistics this term at State College, an 8:00 (AM) section and a 1:30 (PM) section. The final grades for both sections are summarized in the contingency table below.
Observed Frequencies: Oi's
| A | B | C | D | F | Totals | |
| AM | 6 | 11 | 17 | 19 | 18 | 71 |
| PM | 19 | 20 | 17 | 12 | 9 | 77 |
| Totals | 25 | 31 | 34 | 31 | 27 | 148 |
The Test: Test for a significant dependent relationship between grades and the section of the course. Conduct this test at the 0.05 significance level.
(a) What is the null hypothesis for this test?
H0: The section (AM/PM) of a course and the grades are dependent variables.H0: The section (AM/PM) of a course and the grades are independent variables.
(b) What is the value of the test statistic? Round to 3
decimal places unless your software automatically rounds to 2
decimal places.
χ2
=
(c) Use software to get the P-value of the test statistic.
Round to 4 decimal places unless your software
automatically rounds to 3 decimal places.
P-value =
(d) What is the conclusion regarding the null hypothesis?
reject H0fail to reject H0
(e) Choose the appropriate concluding statement.
We have proven that grades and section of the course are independent.The evidence suggests that there is a significant dependent relationship between grades and the section of the course. There is not enough evidence to conclude that there is a significant dependent relationship between grades and the section of the course.

Price Elasticity of Demand:
Choose a product that you regularly purchase and decide whether the
demand for the product is elastic, inelastic or unit elastic based
on your knowledge of price elasticity of demand. Explain the
factors that you think cause the good or service to be elastic,
inelastic or unit elastic in detail (related to the determinants of
price elasticity of demand). Also, describe the shape of the demand
curve and explain what producers in this industry should do to
their prices to increase their total revenue. Please use an
original example (not one that has been used in the textbook/power
points) or you will lose points. Remember, you must do your own
work in this class on all assignments so resist the temptation to
use outside websites to copy information as that would be
plagiarism. Go to your book and power points first as a resource
for your research.
Please help? I don't know how to start this . Just for a few paragraph ...I choose to talk about Make up foundation.
