Discussion 4: Null and Alternative Hypotheses Previous Next Describe how to write the null and alternative hypotheses based on a claim. Provide at least one example to clarify your explanation. *Read the majority of posts from your classmates and choose two to respond to (with a minimum of 3 sentences each). Your response should be well thought out and further the discussion. Start a New Thread
Part I. Constructing a Null and Alternative Hypothesis: Write a pair of null and alternative statistical hypothesis (can be about any topic).
A biologist believes that there has been increase in the mean total suspended solids (TSS, mg/L) among Philippine rivers since its last study, where a mean 80 mg/L of TSS was observed. A random sample of 25 rivers was observed and the mean TSS was found to be 100 mg/L. Suppose it is of interest to test the biologist claim, the appropriate pair of null and alternative hypotheses is O Ho: µ-80, Ha: μ>80 O Ho: μ-100, Ha: µ>100 O Ho: X-bar = 80, Ha: X-bar > 80 O Ho: X-bar = 100, Ha: X-bar > 100
A recent study at a university showed that the proportion of students who commute more than 15 miles to school is 25%. Suppose we have good reason to suspect that the proportion is greater than 25%, and we carry out a hypothesis test. State the null hypothesis H, and the alternative hypothesis H, that we would use for this test. Ho: 0 H;: D O
The mean weight of male aerobics instructors in a certain city is less than 185 lbs. Express the null and alternative hypotheses in symbolic form for this claim.
16. Researchers claim that 60 tissues are the average number of tissues a person uses during the course of a flu. The company who makes Kleenex brand tissues thinks that fewer of the tissues are needed. What are their null and alternative hypotheses? llatra) o A. Ho: u=60 vs Ha: µ>60 on10 B.

13% of all Americans suffer from sleep apnea. A researcher suspects that a different percentage of those who live in the inner city have sleep apnea. Of the 390 people from the inner city surveyed, 70 of them suffered from sleep apnea. What can be concluded at the level of significance of a = 0.10? b. The null and alternative hypotheses would be: Ho: ? 8 Select an answer O |(please enter a decimal) H1: ? E Select an answer O (Please enter a decimal) c. The test statistic ? 6 (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? O a f.

Identify the null and alternative hypothesis(in symbolic and sentence form), test statistic, P-value(or critical values), conclusion about the null hypothesis, and final conclusion that addresses the original claim(Don’t just say Reject the null hypothesis or fail to reject the null hypothesis). If you used the calculator, identify everything mentioned above in addition to which calculator functions and inputs for each field were used. In a clinical study of an allergy drug, 108 of the 202 subjects reported experiencing significant relief from their symptoms. At the 0.01 significance level, test the claim that more than half of all those using the drug experience relief.
Of which test is the Friedman test a nonparametric version?
