Carefully state the null and alternative hypotheses of this test and find the missing values *, **, ***, ****, ***** What is the conclusion for this test? Give reasons for your answer.
after checking the hypothesis tests, please explain briefly how you should proceed given the result of recent hypothesis tests and what the owner should do
A scorlarship requires applicants to get a score at the 90th percentile or above on a certain standadized test in order to qualify. Angela gets a score of 177 out of 200 possible points on the test. Did Angela definitely qualify, definely not qualify, or is there not enough information to determine wheter or not she qualified? Explain.
A data set includes data from 500 random tornadoes. The display from technology available below results from using the tornado lengths (miles) to test the claim that the mean tornado length is greater than 2.4 miles. Use a 0.05 significance level. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. i Click the icon to view the display from technology. Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A. Ho: μ=2.4 miles O B. Ho: μ=2.4 miles H₁: μ#2.4 miles H₁: μ 2.4 miles Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. (Round to three decimal places as needed.) State the final conclusion that addresses the original claim. Ho. There is greater than 2.4 miles evidence to support the claim that the mean tornado length is
Identify the null and alternative hypothesis(in symbolic and sentence form), test statistic, P-value(or critical values), conclusion about the null hypothesis, and final conclusion that addresses the original claim(Don’t just say Reject the null hypothesis or fail to reject the null hypothesis). If you used the calculator, identify everything mentioned above in addition to which calculator functions and inputs for each field were used. A researcher wishes to determine whether the blood pressure of vegetarians is, on average, lower than the blood pressure of nonvegetarians. Independent simple random samples of 85 vegetarians and 75 nonvegetarians yielded the following sample statistics for systolic blood pressure. Test the claim that vegetarians have lower blood pressure than non vegetarians. Use a 0.05 level of significance. Vegetarians Non Vegetarians n=85 n=75 Mean=124.1mmHg Mean=138.7mmHg St dev=38.7mmHg St dev=39.2mmHg
If a hypothesis is not rejected at the 5% level of significance, it a) will always be rejected at the 1% level O b) will also not be rejected at the 1% level O c) will sometimes be rejected at the 1% level d) None of these alternatives is correct.
Suzette does an experiment where she collects date from 5 women snd obtains the scores: 4, 4, 5, 2, 5. She hypothesizes that the population mean for the population from which these scores are drawn is 3. She wants to test whether this hypothesis is true. What is the alternative hypothesis she is testing?
Can you help me with the code for this in R please? 2. The article ["CSI Effect Has Juries Wanting More Evidence" (USA Today, 2004)](https://usatoday30.usatoday.com/news/nation/2004-08-05-csi-effect_x.htm) examines how the popularity of crime-scene investigation television shows in influencing jurors' expectation of what evidence should be produced at a trial. In a survey of 500 potential jurors, one study found that 350 were regular watchers of at least one crime-scene forensics television series. i) Assuming that it is reasonable to regard this sample of 500 potential jurors as representative of potential jurors in the US, use the given information to construct and interpret a 95\% confidence interval for the proportion of all potential jurors who regularly watch at least one crime-scene investigation series. ii) Using the same sample proportion as part (i), construct a 95\% confidence interval for same proportion but instead use a sample size of 50. iii)…
