Description
An instructor has found that grades on the final exam for a course are normally distributed with a mean of 63 (out of 100) and a standard deviation of 11.5. The pass mark for the exam is 50.
The exam consists of 24 multiple-choice questions, each with 3 possible answers of which only 1 is correct.
Part 1 - How many students in a typical class of 30 would you expect to fail?
Part 2 - A student knows the answer to 12 of the questions, but has to guess at the other 12. What’s the probability that this student ends up in the top 10% of the class?

Week 5 (and final assignment)
You are the manager of a retail store. You want to investigate how metrics can improve the way you manage your business.Use the Week 5 Data Set to create and calculate the following in Excel®:Conduct a goodness of fit analysis which assesses orders of a specific item by size and items you received by size.Conduct a hypothesis test with the objective of determining if there
is a difference between what you ordered and what you received at the
.05 level of significance. Identify the null and alternative hypotheses.Generate a scatter plot, the correlation coefficient, and the linear
equation that evaluates whether a relationship exists between the
number of times a customer visited the store in the past 6 months and
the total amount of money the customer spent.Set up a hypothesis test to evaluate the strength of the relationship between the two variables.Use a level of significance of .05.Use the regression line formula to forecast how much a customer
might spend on merchandise if that customer visited the store 13 times
in a 6 month period. Consider the average monthly sales of 2014, $1310,
as your base to:Calculate indices for each month for the next two years. Graph a time series plot.In the Data Analysis Toolpak, use Excel's Exponential Smoothing option.Apply a damping factor of .5, to your monthly sales data. Create a new time series graph that compares the original and the revised monthly sales data.

Scenario Analysis, statistics homework help
Scenario:The owner of a small printing
company is considering the purchase of additional printing equipment to expand
her business. If the owner expands the business and sales are high, projected
profits (minus the cost of the equipment) should be $90,000; if sales are low,
projected profits should be $40,000. If the equipment is not purchased,
projected profits should be $70,000 if sales are high and $50,000 if sales are
low.
Are there options other than the purchase of additional
equipment that should be considered in making the decision to expand the
business?
If the owner is optimistic about the company’s future
sales, should the company expand by purchasing the equipment?
Is the owner’s optimism or pessimism about sales the
only factor that may impact the company’s profits?
The equipment to be purchased is known in the industry
to have a useful life of five years. How might this impact the printing
company?

The National Health Survey uses household interviews to describe the health-related habits of U.S. adults. From these interviews they estimate population parameters associated with behaviors such as alcohol consumption, cigarette smoking, and hours of sleep for all U.S. adults.
In the 2005-2007 report, they estimated that 30% of all current smokers started smoking before the age of 16. Imagine that we want to verify this estimate. So we randomly select a sample of 100 smokers and calculate the proportion who started smoking before the age of 16. How much error do we expect in the sample proportions if the 30% is correct for the population overall? Use the applet and a give an error based on 2 standard deviations.
