A ten-year study found that the proportion of high school seniors who believed "getting rich" was an important personal goal was70%. Suppose we have reasonto believe that this ratio has changed and we want to perform a hypothesis test to see if this can be supported. Formulate the null hypothesish and thealternative hypothesish that would be used to perform this test.ho: 0h₁:0μ<2OSOхрO SXO

Determine if the following statement is true or false. If you believe that the statement is false, briefly explain why you think it is false. Small values of x² imply that the null hypothesis in a chi-squared test is true. Choose the correct answer below. A. The statement is true. B. The statement is false because hypothesis tests do not prove the truth of the null hypothesis. C. The statement is false because the value of x² is not considered when determining whether the null hypothesis is true. D. The statement is false because large values of x² imply that the null hypothesis is true.
A real estate agent compares the selling prices of homes in two municipalities in southwestern Pennsylvania to see if there is a difference. The results of the study are shown. Is there enough evidence to reject the claim that the average cost of a home in both locations is the same? Use a=0.10. Use a TI-83 Plus or TI-84 Plus calculator.

A hypothesis test is a process that uses sample statistics to test a claim about the value of a population parameter. Researchers in fields such as medicine, psychology, and business rely on hypothesis testing to make informed decisions about new medicines, treatments, and marketing strategies. 1. A random sample of 50 students who took an…
One of the advantages of understanding statistics is that you can apply the concepts to yourself. This is even easier to do during our present time because of the widespread use of wearables. Wearables are accessory devices or clothing with embedded technology that are worn by a person and used to provide feedback to the person wearing them. Examples include the Fitbit, which is worn on the wrist and gathers data such as number of steps walked, heart rate, sleeping time. Another example is Ambiotex's smart shirt which is designed for athletes and has sensors in the shirt to measure heart rate, anaerobic threshold, fitness and stress levels. There are other companies making similar products. Suppose that you are interested in the amount of sleep you get a night. Sleep is very important and there is evidence that many Americans do not get enough sleep. You hypothesize you get 6 hours of sleep a night. Using a wearable, you track your amount of sleep on 16 random nights. Test the…

The proportion of people who live after fighting cancer is 0.75. Suppose there is a new therapy that is used to increase the survival rate. Use the parameter p to represent the population portion of people who survive after fighting cancer. For a hypothesis test of the therapy’s effectiveness, researchers use a null hypothesis of p = 0.75. Pick the correct alternative hypothesis. 1. p > 0.75 2. p < 0.75 3. p 6= 0.75
