Write the null and alternative hypotheses you would use to test the following situation. A weight loss center provided a loss for 72% of its participants. The center's leader decides to test a new weight loss strategy to see if it's better. What are the null and altemative hypotheses? O A. Ho: p = 0.72 HA: P#0.72 O B. Ho: p> 0.72 HA:p< 0.72 OC. Ho:p= 0.72 HA:p> 0.72 O D. Ho: p = 0.72 HA:p<0.72 O E. Ho: p>0.72 HA:P= 0.72

Internet tax: The Gallup Poll asked 1043 U.S. adults whether they believed that people should pay sales tax on items purchased over the internet. Of these, 407 said they supported such a tax. Does the survey provide convincing evidence that the percentage of U.S. adults who favor an internet sales tax differs from 40%? Use the a = 0.05 level of significance. Part 1 of 5 State the appropriate null and alternate hypotheses. Ho: p = 0.40 H:p = 0.40 This hypothesis test is a two-tailed test. Part: 1/5 Part 2 of 5 Find the critical values. Round the answers to at least three decimal places. For a = 0.05, the critical values are and
This is a _______ tailed test. The correct statistical test to use for this problem is: Hypothesis testing: The last part of the null and alternative hypotheses are: What is/are the critical values for this problem? What is the obtained statistic for this problem? The effect size for this problem is _______.
According to a recent study in New York, 15% of shoppers are unfairly being charged sales tax in non-taxable items. Mr. Hypothesis feels this proportion is too low. He tests his belief by conducting a survey of 200 random shoppers. Which of the following is the null hypothesis? a. The percent of shoppers unfairly being charged sales tax on non-taxable items < .15 b. The percent of shoppers unfairly being charged sales tax on non-taxable items > .15 c. The percent of shoppers unfairly being charged sales tax on non-taxable items = .15
Abnormalities In the 1980s it was generally believedthat congenital abnormalities affected about 5% of thenation’s children. Some people believe that the increasein the number of chemicals in the environment has ledto an increase in the incidence of abnormalities. A recentstudy examined 384 children and found that 46 of themshowed signs of an abnormality. Is this strong evidencethat the risk has increased?a) Write appropriate hypotheses.b) Check the necessary assumptions.c) Perform the mechanics of the test. What is theP-value?d) Explain carefully what the P-value means in context.e) What’s your conclusion?f) Do environmental chemicals cause congenitalabnormalities?

A decade-old study found that the proportion of high school who felt that ‘getting rich was an important personal goal was 75%. Suppose that we have reason to believe that this proportion has changed., and we wish to carry out a hypothesis test to see if our belief can be supported. State the thanks hypothesis H0 and the alternative H1 that we would use for this test.
According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in 2007 were for identity theft. In that year, Alaska had 321 complaints of identity theft out of 1,432 consumer complaints ("Consumer fraud and," 2008). Does this data provide enough evidence to show that Alaska had a lower proportion of identity theft than 23%? Test at the 5% level.
