In some area of interest to you (not from the text), create a hypothetical experiment to resolve a claim about a population with sampling of data and a hypothesis test. Describe the claim, the experiment, the test statistic, and clearly state the null and alternative hypotheses. In fact, the outline of a good response looks like this:
I) Description of problem and statement of claim
II) Statement of null hypothesis
III) Statement of alternative hypothesis
IV) Description of experiment and sampling plan
V) Description of test statistic and the form of the actual test with critical value(s)
Test the hypothesis that more than 60 percent of the U.S. senators (of a total 100 senators) favor the president's economic plan, if a sample of 40 showed that 22 favor the plan (use alpha = .05).
Rental car gasoline prices per gallon were sampled at eight major airports. Date for Hertz and National car rental companies follow (USA today April 4, 2000)
Show all the steps of your hypothesis test including a) the claim being tested , b) the null and alternative hypothesis, c) the test statistic, d) the p value, e) initial conclusion, and f) a final conclusion about the original claim.
When assigning probabilities of two simple events, can we assume that each event is always equally likely to occur and, thus assign .5 to each event?
Use the traditional method to test the given hypothesis. Assume that the population is the normally distributed and that the sample has been randomly selected.
Let X be the number of correct guesses by your friend in the 100 trials and Use the Normal approximation with the continuity correction - Which of the following might be reasonably modeled by the binomial distribution
If an auditor takes a random sample of 36 accounts what is the probability that the mean balance will be less than 45?
The information is reported below. Is it reasonable to conclude the percent is less now than five years ago?
What assumption about the population distribution is needed in order to conduct the t test in (a)?
What is the shape mean and standard deviation of the resulting distribution of the sample mean? What is the probability that the mean of the sample of 42 is more than 52 hours?
Use the above information to calculate the number of watches (units) and the sales dollars we need in order for our flea market business to break even for the day.
What assumption must you make about the population distribution in order to construct the confidence interval estimate in (a)?
