Could you please help me out with this question… Does ivy grow better in areas with more sun versus in shady areas? Formulate one null (H0) and one alternative (H1) hypothesis.
An economist has collected data on the number of house foreclosures. The published share of housing units with a foreclosure filing is 0.47%. The economist believes, based on the data she collected, that the share of housing units with a foreclosure filing is different from 0.47%. What are the null and alternative hypotheses? Select the correct answer below: H0: μ≠0.47%; Ha: μ=0.47% H0: μ=0.47%; Ha: μ≥0.47% H0: μ=0.47%; Ha: μ≤0.47% H0: μ=0.47%; Ha: μ≠0.47%
A certain medicine company wants to determine that if a drug has the undesirable side effect of reducing the blood pressure of the patient. The research involves recording the initial blood pressure 12 certain aged patients. Then, these patients took the druh by the advise of the doctors and at the end of their useahe, the blood pressures of them again recorded. The company would like to draw inferences about the effect of the drug on the blood pressure based on the following data: Patients Blood Pressure 1 2 3 4 5 6 7 8 9 10 11 12 Before usage (x) 77 72 80 64 70 76 72 82 78 74 74 76 After uesage (y) 70 62 72 72 68 66 68 74 52 74 74 58 a) Calculate a 90% CI for the mean reduction in blood pressure. Round your answer to 1 decimal point. b) Do the data provide significant evidence toward the claim on the use of the drug reduces blood pressure? Test at = 0.10. We accept Ho We do not accept Ho
You wish to test the hypothesis that female college students spend more on wearing apparel than male college students. Which of the following is INCORRECT? The null and alternate hypotheses are:Ho : mF < = mMHA : mF > mM If you concluded that female students spend more than male students when in fact there is no difference between the two groups, you would be committing a Type II error. If we conclude that females spend less than males when in fact that is the case, we have made a correct decision. If in testing the above hypothesis, we insist on reducing the probability of making the Type I error, ceteris paribus the probability of Type II error will increase.
A golf instructor claims that more than 70% of his students have improved their driving distance by at least 20 yards after viewing and applying the techniques described in his instructional video. If 138 out of 180 viewers say that their driving distance has improved by at least 20 yards, is the instructor's claim valid? Identify the null and alternative hypotheses for this scenario. Is the instructor's claim that "more than 70% of his students have improved their driving distance by at least 20 yards," valid? Your response should include your decision and conclusion in context of the scenario.
If a null hypothesis is rejected at the 0.05 level of significance, it must be rejected at the 0.01 level. True or False?
The following are the hypotheses for a test of the claim that college graduation statue and cola preference are independent. H0: College graduation status and cola preference are independent. H1: College graduation status and cola preference are dependent. If the test statistic is χ2=0.579 and the critical value is χ2=5.991, what is your conclusion about the null hypothesis and about the claim? A. Fail to reject the null hypothesis. There is sufficient evidence to warrant rejection of the claim that college graduation status and cola preference are independent. B. Reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim that college graduation status and cola preference are independent. C. Fail to reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim that college graduation status and cola preference are independent. D. Reject the null hypothesis. There is sufficient…
Let us hypothesize that cats spend more time sleeping in Winter than in Summer. Let us also presume that in Summer, cats sleep an average of 15 hours per day and we will be observing the sleep patterns of cats during Winter for comparison. Using the notation below, identify the four possible hypotheses. Then describe each of those hypotheses within the context of this cat-sleep study. H0: µ=µhyp Halt: µ ≠µhyp Halt2: µ>µhyp Halt3: µ<µhyp
Q3. If the null hypothesis is not rejected when the null hypothesis is in error, what type of error, if any, has been made?
A company manager wants to compare the satisfaction levels of his customers from two stores belonging to his company. According to his research, 249 out of 300 people are satisfied with shop A, and 348 out of 400 people are satisfied with shop B. Which of the following hypothesis states that there is a significant difference between customer satisfaction levels? H0 : P1 < P2, H1 : P1 ≥ P2 H0 : P1 ≥ P2, H1 : P1 < P2 H0 : P1 > P2, H1 : P1 < P2 H0 : P1 = P2, H1 : P1 ≠ P2 H0 : P1 ≠ P2, H1 : P1 < P2
The mayor of a town has proposed a plan for the construction of an adjoining bridge. A political study took a sample of 900 voters in the town and found that 48% of the residents favored construction. Using the data, a political strategist wants to test the claim that the percentage of residents who favor construction is not equal to 51%. Testing at the 0.05 level, is there enough evidence to support the strategist's claim? Step 1 of 6 : State the null and alternative hypotheses.
