Questions 1 and 2: Set up the Null and Alternative hypotheses to test the following claims: 1. A health insurance company wants to determine if more than 25% of U.S. residents have been to a hospital emergency room within the past year. State the null and alternative hypotheses. H0: HA: 2. A company makes canned clam chowder (a delicious New England tradition). On the label, the company claims that the chowder contains (on average) 3.5 grams of Total Fat per serving. A consumer group would like to test this claim is true. State the null and alternative hypotheses that you would use to test if the mean amount of Total Fat per serving differs from 3.5 grams: H0: HA:

State the alternative hypotheses for the following claim: For Division I schools, less than 25% of them have a bulldog as their mascot.

What is the final conclusion? O A. There is not sufficient evidence to support the claim that less than 26% of offspring peas will be yellow. O B. There is not sufficient evidence to warrant rejection of the claim that 26% of offspring peas will be yellow. O C. There is sufficient evidence to support the claim that less than 26% of offspring peas will be yellow. O D. There is sufficient evidence to warrant rejection of the claim that 26% of offspring peas will be yellow.

On a state driver’s test, about 45% pass the test on the first try. We want to test if more than 45% pass on the first try. Fill in the correct symbol (=, ≠, ≥, <, ≤, >) for the null and alternative hypotheses

You conduct a hypothesis test. Assuming you have made no errors in your calculations, what should we conclude if the test statistic ends up being positive?    The claimed population proportion must be large. The sample proportion is larger than (or greater than) the claimed population proportion. The sample proportion is smaller than (or less than) the claimed population proportion. The sample size must be large. The claimed population proportion must be small.

1) A sample of n = 200 college students are asked if they believe in extraterrestrial life and 120 of these students say that they do. The data are used to test if more than half of college students believe in extraterrestrial life. a. State the null and alternative hypothesis.   b. Give the P- value   c. Give a conclusion for the hypothesis test

Graduation Rates. Use the technology of your choice to perform the tests of hypotheses in parts (a) and (b).

Question 6 In this exercise, we are conducting many hypothesis tests to test a claim. Assume that the null hypothesis is true. If 100 tests are conducted using a significance level of 5%, approximately how many of the tests will incorrectly find significance?Enter your answer in accordance to the question statement of the tests will find significance.

Many questions in research can be expressed as two competing statements about the population parameter. These two statements are called the null and the alternative hypotheses. Usually, the researcher hopes the sample evidence will be in favor of the alternative hypothesis, the new theory. It is important to be able to state the theories that are being put to a test.    Suppose that 40% of all supermarkets in the US use recyclable plastic bags. We would like to assess if the proportion of supermarkets in Michigan that use recyclable plastic bags is more than the stated rate. For this scenario, write out the hypotheses to be put to the test and define the parameter of interest in context of the problem. H0:Ha: The parameter p represents ___(provide appropriate definition in context)________

Consumers Energy states that the average electric bill across the state is $60.07. You want to test the claim that the average bill amount is actually greater than $60.07. What are the appropriate hypotheses for this test?   Question 12 options:   1)  HO: μ ≥ 60.07HA: μ < 60.07   2)  HO: μ = 60.07HA: μ ≠ 60.07   3)  HO: μ > 60.07HA: μ ≤ 60.07   4)  HO: μ ≤ 60.07HA: μ > 60.07   5)  HO: μ < 60.07HA: μ ≥ 60.07
