(1 point) According to a recent marketing campaign, 100 drinkers of either Diet Coke or Diet Pepsi participated in a blind taste test to see which of the drinks was their favorite. In one Pepsi television commercial, an anouncer states that "in recent blind taste tests, more than one half of the surveyed preferred Diet Pepsi over Diet Coke." Suppose that out of those 100, 42 preferred Diet Pepsi. Test the hypothesis, using a = 0.05 that more than half of all participants will select Diet Pepsi in a blind taste test by giving the following: (a) the test statistic (b) the critical z score
Gender of Interviewer Man Woman Women who agree 578 314 Women who disagree 322 86 Identify the null and alternative hypotheses. Choose the correct answer below. A. H0: The response of the subject and the gender of the subject are independent. H1: The response of the subject and the gender of the subject are dependent. B. H0: The proportions of agree/disagree responses are different for the subjects interviewed by men and the subjects interviewed by women. H1: The proportions are the same. C. H0: The proportions of agree/disagree responses are the same for the subjects interviewed by men and the subjects interviewed by women. H1: The proportions are different. Compute the test statistic. Find the critical value(s). What is the conclusion based on the hypothesis test? Fail to reject/ Reject H0. There is/is not sufficient evidence to warrant rejection of the claim that the…
Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis or (b) fails to reject the null hypothesis? A scientist claims that the mean incubation period for the eggs of a species of bird is at least 34 days. Does the claim represent the null hypothesis or the alternative hypothesis? Since the claim a statement of equality, it represents the V hypothesis.
An opinion poll asked a random sample of high school couples in the United States whether they believe they will marry their high school sweetheart. A researcher believes more than 25% of high school couples believe they will marry. Which null and alternative hypotheses should be used to test this claim?

HYPOTHESIS TESTING 1. Formulate the null and the alternative Ho: hypotheses In symbol: Ho: μ = 50 Ha: The average weight of bag of chemical is not equal to 50 kilograms. In symbol: Ha: 2. Specify the following: A. Level of Significance A. B. Types of Hypothesis Testing [one-tailed test B. two tailed test (left-tailed or right-tailed) or a two-tailed test] 3. Specify the following: A. The test statistic to be used. (t-test: one sample mean or t-test: two sample means) A. B. Find the Degree of Freedom Formula: df = n-1 (for one-sample mean test) B. df = n -1 df = (n + n₂) - 2 (for two-sample mean test) df = 16-1 C. The critical or tabular value (t critical). (Can be found on the given table of Tabular Value of T) df = 15 C. 2.947 4. Compute for the value of the test statistic Formula: (t computed) using the data from the population (x-μ)√n t= and the sample/s. Given: хэ 48.1 μl - n-29 s-0.9 Substitute the given to the formula and solve:

Consumers Energy states that the average electric bill across the state is $67.16. You want to test the claim that the average bill amount is greater than $67.16. The hypotheses for this situation are Null Hypothesis: u = 67.16, Alternative Hypothesis: u > 67.16. If the true statewide average bill is $51.28 and the null hypothesis is not rejected, did a type I, type II, or no error occur? a No error has occurred. b Type I Error has occurred. c Type II Error has occurred. d We do not know the p-value, so we cannot determine if an error has occurred.
A hypothesis test is to be performed. Describe the two possible outcomes of the test using the context of the given situation.Last month the average waiting time at a bank was 8.4 minutes. The manager has installed a new computer system and claims that people will no longer have to wait as long. The hypotheses are as follows:Null hypothesis: average waiting time = 8.4 minutes Alternative hypothesis: average waiting time < 8.4 minutes Rejecting the null hypothesis means there is insufficient evidence that the mean waiting time is equal to 8.4 minutes. Accepting the null hypothesis means there is evidence to conclude that the mean waiting time is equal to 8.4 minutes. Rejecting the null hypothesis means there is evidence that the mean waiting time is not equal to 8.4 minutes. Failing to reject the null hypothesis means there is insufficient evidence to conclude that the mean waiting time is less than 8.4 minutes. Rejecting the null hypothesis means there is…
