Hi, I need help with essay on STAT. Paper must be at least 1500 words. Please, no plagiarized work!

The mean credit card debt among households in one state is $8400. A hypothesis test is to be performed to decide whether the mean credit card debt for households in the formerly affluent town of Rich-No-More differs from the mean credit card debt for the state

At one school, in 2005, the average amount of time that tenth-graders spent watching television each week was 21.6 hours. The principal introduced a campaign to encourage the students to watch less television. One year later, in 2006, the principal performed a hypothesis test to determine whether the average amount of time spent watching television per week had decreased. The hypotheses are:

A correct decision would occur if, in fact, μ = 21.6 hours, and the results of the sampling do not lead to rejection of that fact. or if, in fact, μ &lt. 21.6 hours and the results of the sampling lead to that conclusion.

A correct decision would occur if, in fact, μ = 21.6 hours, and the results of the sampling do not lead to rejection of that fact. or if, in fact, μ &lt. 21.6 hours and the results of the sampling do not lead to rejection of the null hypothesis that μ = 21.6 hours.

A correct decision would occur if, in fact, μ = 21.6 hours, and the results of the sampling lead to rejection of the null hypothesis. or if, in fact, μ &lt. 21.6 hours and the results of the sampling lead to that conclusion.

A sample mean, sample size, and population standard deviation are given. Use the one-mean z-test to perform the required hypothesis test about the mean, μ, of the population from which the sample was drawn.

A researcher wishes to estimate the proportion of people within a certain population who are in favor of a national health care system. Obtain a sample size that will ensure a margin of error of at most 0.01 for a 95% confidence interval.

A nationwide study of American homeowners revealed that 65% have one or more lawn mowers. A lawn equipment

Description for Quiz 9

Suppose the number of equipment sales and service contracts that a store sold during the last six (6) months for treadmills and exercise bikes was as follows:

                       Treadmill          Exercise Bike

Total sold                  195                           138

Service contracts       60                             45

The store can only sell a service contract on a new piece of equipment. Of the 195 treadmills sold, 60 purchased a service contract. Of the 138 exercise bikes, 45 purchased a service contract.

Remember to watch the instructional video and use the excel template provided to help you with the math.

Complete the following questions in the space provided below:

  1. Is there a major difference between the two pieces of equipment? Why or why not?
  2. Interpret the meaning of the confidence interval for Treadmills at a 95% confidence level.
  3. Interpret the meaning of the confidence interval for Exercise Bikes at a 95% confidence level.
  4. Are confidence intervals one-tailed or two-tailed?
  5. Construct a 95 percent confidence interval for the difference between the proportions of service contracts sold on treadmills versus exercise bikes.

At the conclusion of Chapter 13, the monster realizes that he has none of the qualities or possessions that human beings value, and so he worries the he will be forever miserable. He says, “Oh, that I had for ever remained in my native wood, nor known nor felt beyond the sensations of hunger, thirst, and heat!” This statement recalls one made by Victor Frankenstein in Chapter 10: “If our impulses were confined to hunger, thirst, and desire, we might nearly be free; but now we are moved by every wind that blows, and a chance word or scene that that word may convey to us.” What do these two statements suggest about the impact of knowledge? How do the statements affect the way readers view the monster and Victor?
