A hypothesis testing: H0: p=0.49 HA: p<0.49.
We conduct a survey with sample size n=171 and have pˆ=0.39. With α=0.05, do you reject or fail to reject the Null hypothesis? Enter 1 if you "reject the Null hypothesis" and 0 if you "fail to reject the null hypothesis".
Note:
1- Enter either 0 or 1 in the box. The box does not accept text as an answer. Your answer should be either 0 or 1 and no other answers will be accepted.

The following hypotheses are given. H0: p ≤ 0.49 H1: p > 0.49 A sample of 142 observations revealed that = 0.39. At the 0.10 significance level, can the null hypothesis be rejected? a. State the decision rule. (Round the final answer to 3 decimal places.) Reject Correct H0 and and accept Correct H1 if z > 1.28 1.28 Incorrect or z < 1.28 1.28 Incorrect . b. Compute the value of the test statistic. (Round the final answer to...
A hypothesis test is used to test the hypotheses H0: μ = 10.5 versus HA: μ > 10.5 where μ = the mean weight of a one-year old tabby cat. Based on a random sample of 21 cats, a p-value of 0.0234 is found. a) Using α = 0.05, what is the conclusion for this test, reject or fail to reject the null hypothesis? b) Based on your answer to part b, what type of error did you possibly make,...
In testing Null hypothesis H0:β2=10 H 0 : β 2 = 10 and alternative hypothesis H0:β2≠10 H 0 : β 2 ≠ 10 using a 1% significance level, you find a p-value of 0.05. What should you conclude? Select one: a. There is not sufficient evidence to reject null hypothesis (H0) so we maintain the null hypothesis by default. b. H0 is not true, and thus β2=c. β 2 = c . c. H0 should be rejected and is unlikely...
n = 81 s2 = 625 H0: σ2 = 500 Ha: σ2 ≠ 500 9. The test statistic equals a. 100 b. 101.88 c. 101.25 d. 64 10. The p-value is between a. 0.025 and 0.05 b. 0.05 and 0.1 c. 0.1 and 0.2 d. 0.2 and 0.3 11. What is your conclusion? Use α = 0.05. a. fail to reject the null hypothesis b. reject the null hypothesis
Assume a significance level of α=0.05 and use the given information to complete parts (a) and (b) below.Original claim: Less than 56% of adults would erase all of their personal information online if they could. The hypothesis test results in a P-value of 0.0476.Question content area bottomPart 1a. State a conclusion about the null hypothesis. (Reject H0 or fail to reject H0.) Choose the correct answer below.A.Fail to reject H0 because the P-value is greater than α.B.Reject H0 because the ...
Assume a significance level of α=0.05 and use the given information to complete parts (a) and (b) below.Original claim: The mean pulse rate (in beats per minute) of a certain group of adult males is 71 bpm. The hypothesis test results in a P-value of 0.0896.Question content area bottomPart 1a. State a conclusion about the null hypothesis. (Reject H0 or fail to reject H0.) Choose the correct answer below.A.Reject H0 because the P-value is less than or equal to α.B.Reject...
Consider the following hypothesis test. H0: μ1 − μ2 = 0 Ha: μ1 − μ2 ≠ 0 The following results are for two independent samples taken from the two populations. Sample 1 Sample 2 n1 = 80 n2 = 70 x1 = 104 x2 = 106 σ1 = 8.4 σ2 = 7.2 (a) What is the value of the test statistic? (Round your answer to two decimal places.) (b) What is the p-value? (Round your answer to four decimal places.)...
Suppose that you are testing the hypotheses Upper H0: p=0.33 vs. HA: p>0.33 A sample of size150 results in a sample proportion of 0.39 a) Construct a 99% confidence interval for p. b) Based on the confidence interval, can you reject H0 at αequals=0.005?Explain. c) What is the difference between the standard error and standard deviation of the sample proportion? d) Which is used in computing the confidence interval?
A test is conducted with alternative hypothesis Ha: μ > 85, and the p-value is p = 0.007. Would you reject or fail to reject H0 at the 0.01 level of significance? Group of answer choices reject H0 not sufficient information to decide fail to reject H0
onsider the hypothesis test below. H0: p 1 - p 2 ≤ 0 Ha: p 1 - p 2 > 0 The following results are for independent samples taken from the two populations. Sample 1 Sample 2 n1 = 200 n2 = 400 p1 = 0.23 p2 = 0.16 What is the value of the test statistic (to 2 decimals)? What is the p-value (to 4 decimals)? With α = .05, what is your hypothesis testing conclusion?
