- 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? O Ho: p = 0.25, Ha: p > 0.25 O Ho: p = 0.25, Ha: p 0.25, Ha: p = 0.25 O Ho: P = 0.25, Ha: p > 0.25How do you write a null hypothesis and an alternative hypothesis in words? This is the question: The survey question: On the average day, about how many hours do you personally watch television? Suppose that your reading of professional research on the topic leads to the hypothesis that, on average, adults in the US watch three hours of TV each day. I planned to use a two-sided alternative hypothesis. In symbol, my null hypothesis would be H0 : equal 3 and my alternative hypothesis would be Ha not equal 3

- Several recent studies have suggested that people who suffer from abnormally high blood pressure can benefit from regular exercise. She conducts a small sample of 3 random patients with high blood pressure and measures blood pressure before and after the exercise program. Subject Before After 1 155 133 2 160 140 3 145 120 Conduct a test to see if the claim is supportive. State the hypotheses from the previous problem. (high blood pressure problem)The null hypothesis when testing for a single population can take many forms depending on the parameter being studied. If the parameter of interest is the population mean, which statement best represents the original claim that the parameter equals a given value, k?Number 1
- 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…which of the following statements are true about ALTERNATE hypotheses? Please select all that apply. They posit that any relationship we observe between two variables is true in the population but not necessarily in samples from that population. They posit that there is a relationship between two variables in the population. They posit that any relationship we observe between two variables is the result of random chance They posit that any relationship we observe between two variables is not the result of random chance They posit that there is no relationship between two variables in the population. which of the following statements about p values are correct? Please select all that apply. They imply larger effect sizes They prove that the alternate hypothesis is true They correspond to the probability that we would observe a relationship between two variables in our sample, if there was no true relationship between them in the population They prove that the null hypothesis is true…
