The 92 million Americans of age 50 and over control 50 percent of all discretionary income. AARP estimates that the average annual expenditure on restaurants and carryout
food was $1,876 for individuals in this age group. Suppose this estimate is based on a sample of 80 persons and that the sample standard deviation is $550. Round your
answers to the nearest whole numbers.
a. At 99% confidence, what is the margin of error?
b. What is the 99% confidence interval for the population mean amount spent on restaurants and carryout food?
C. What is your estimate of the total amount spent by Americans of age 50 and over on restaurants and carryout food?

A standard 6-sided die is rolled and a coin is flipped. Write the sample space as a set of outcomes.
Write each outcome as the die value followed by the coin state. For example, 6 and Heads would be
written as 6H. Separate answers with a comma and use standard set notation by surrounding the list with
brackets { }.
Let A be the event that the coin comes up tails, Let B be the event that a 5 is rolled on the die.
Write A as a set of outcomes. It should be a subset of the sample space above.
What is the probability of the coin landing on tails?

Instructor Example:
We were introduced to hypothesis testing. We will continue our study this week. Hypothesis testing is very similar to a criminal
trial, where a jury must use evidence to decide which of 2 possibilities is the truth: innocence (H0) or guilt (HA).
In your initial post, address the following prompts:
Describe a hypothesis test study that would help your work or conclusions in some way.
Describe what variable would be tested and what would be your guess of the value of that variable.
Discuss how the result, if the null was rejected or not, might change your conclusions or actions in some way.
