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
Networking - A 2016 study conducted by LinkedIn found that 85% of all jobs are filled via networking - the process of interacting with others to develop professional contacts. Marie is skeptical of this study, and believes that the actual percentage of jobs filled by networking is actually less than 85%. Marie randomly samples recently filled jobs and finds that 80% of them were filled by networking. She conducts a hypothesis test. The p-value for the test is calculated to...
Assume that a hypothesis test will be conducted using significance level α = .01 and alternative hypothesis Ha: μ : ≠ 19.3. Furthermore, we will use the following sample data: n = 12, x-bar = 18.8, and s = 2.1. Find the p-value for the test. Group of answer choices 0.8540 0.3810 0.5730 0.4270
Test of Significance should include all of the following: -Null and alternative hypothesis stated -Level of significance stated, graph draw with critical region shaded and critical value indicated. (This is related to the lever of significance testing) -Appropriate descriptive statistics of data. -Test statistics (include formula) -test statistic marked on graph -Decision based on p-value. -Non-technical sentence of conclusion and summary. Part 1 Intelligence and the IQ test: A persons IQ was initially defined as follows: Mental age/chronological age *100...
A consumer advocate conducted a hypothesis test at the 5% significance level to determine if the mean level of impurities in a bottled water product is higher than themanufacturer’s advertised value of 20 parts per million. The advocate collected 25samples, measured the impurities, calculated a test statistic and obtained a p-value of 0.0423. Which of the following correctly states the advocate’s conclusion and reason for the conclusion? A. Reject the null hypothesis because the p-value is smaller than the significance...
Identify the null and alternative hypothesis, significance level, test that will be used, test statistic, P-value, conclusion about the null hypothesis, and state the final conclusion that addresses the original claim in nontechnical terms. In a clinical study of an allergy drug, 108 of the 202 subjects reported experiencing significant relief from their symptoms. At the 0.10 significance level, test the claim that more than half of all those using the drug experience relief.
State the null and alternative hypotheses for a hypothesis test, indicate whether the hypothesis test will be left-tailed, ng-tailed or two-tailed and clearly state the two possible conclusions that address the given claim A college professor claims that less than 25% of her students use their phones during class. Which of the following is the hypothesis test to be conducted? O A HOD=025 OBH, p<025 H 0.25 Hp.025 6 C Hạ P = ( 2% OD H:p02 H:p=025 HP<0.25 OL...
A P-value of 0.12 is calculated on a hypothesis test with a significance level set at 0.01. Which of the following is the correct conclusion for the test? a. Claim the null hypothesis is true b. Fail to reject the null hypothesis c. Reject the null hypothesis d. Claim the alternative hypothesis is true Which of the following are not requirements for using the t-distribution for a hypothesis test concerning μ? (More than one answer may be correct.) a. Sample...
Conduct a test at the a=0.05 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the P-value. Assume the samples were obtained independently from a large population using simple random sampling. Test whether pa > P2. The sample data are x = 120, n, 251, x2 = 132 and n, -311 (a) Choose the correct null and alternative hypotheses below O A. Ho P1 =Pz versus H, PP2 OB. Ho P, =...
Suppose a hypothesis test is conducted using a significance or alpha level of 0.05, and the null hypothesis is rejected. This means that? A we would also reject the null hypothesis if the significance level had been 0.10 instead of 0.05. B the p-value was greater than 0.05. C we would also reject the null hypothesis if the significance level had been 0.01 instead of 0.05. D All answer options are correct.
