Determine appropiate test statistic to use and test the hypothesis under 5% significance level. Show work please. The National High School Health Survey (NHSHS) indicates that about 50% of 12th graders consume lessthan 300g of vegetables at lunch, about 40% consume 300-600g, and only 10% of them consume morethan 600g. A high school conducted a survey of student diets and health information, and reported dataabout 12th graders' vegetable intake at lunch:Vegetable Intake in gram Total300g -600g278300gFrequency 150600g98 526

Please answer all sub-parts Clinical trials involved treating patients with Tamiflu, which is a medicine intended to attack the influenza virus and stop it from causing flu symptoms. Among 724 patients treated with Tamiflu, 72 experienced nausea as an adverse reaction. Use a significance level of 0.05 to test the claim that the rate of nausea experienced by patients who were given Tamiflu is higher than the 6% rate experienced by flu patients who were given a placebo.
could you please tell me how to explain to a friend who does not know anything about statistics the relationship between the confidence level expressed as a confidence interval and the level of significance in hypothesis testing. Illustrate the relationship using either the critical value or the p-value approach.thanks
Using the results obtained for a study on website development below, how would we interpret the results of this hypothesis test? The claim is the percent of customers who abandon a web page due to long load times is different from 34%. The significance level is 0.10. The test statistic is 2.50. Select the correct answer below: Reject H0. There is strong evidence to conclude that the percent of customers who abandon a web page due to long load times is greater than 34%. Reject H0. There is NOT strong evidence to conclude that the percentage of customers who abandon a web page due to long load times is greater than 34%. Fail to reject H0. There is strong evidence to conclude that the percent of customers who abandon a web page due to long load times is greater than 34%. Fail to reject H0. There is NOT strong evidence to conclude that the percentage of customers who abandon a web page due to long load times is greater than 34%.

Perform a hypothesis test to determine whether there is a difference in the mean attendance of teams between the two groups created in Part F. Use a 0.05 level of significance in your testing procedures. Hint: When calculating your pooled sample variance and your test statistic, assume the Top 10 data is sample 1 and the Bottom 10 data is sample 2. Decision Rule -t < or t > = REJECT H0 Value of Pooled Sample Variances Value of test statistic Decision: enter Reject or Do Not Reject Is there a difference in the mean attendance between the two groups assuming a 0.05 level of significance? Enter Yes or No. Another variable that can impact attendance is the team's win-loss record. Teams that are winning more games are thought to have increased attendance as fans prefer to see their home team "win" rather than "lose" (although for some teams such as the Chicago Cubs, this is not always an established relationship!).

Applying the Concepts and SkillsIn Exercises, use the technology of your choice toa. conduct a Kruskal–Wallis test on the data at the specified significance level.b. interpret your results from part (a). Note: All data sets are on the WeissStats site.Ground Water. The data from Exercise on the concentrations, in milligrams per liter, of each of four chemicals among three different wells. Use a 1% significance level.In Exercises, use the technology of your choice toa. conduct a one-way ANOVA test on the data.b. interpret your results from part (a).c. decide whether presuming that the assumptions of normal populations and equal population standard deviations are met is reasonable.Ground Water. The U.S. Geological Survey, in cooperation with the Florida Department of Environmental Protection, investigated the effects of waste disposal practices on ground water quality at five poultry farms in north-central Florida. At one site, they drilled four monitoring wells, numbered 1, 2, 3, and 4.…
Explain the difference between hypothesis testing with test statistics vs. hypothesis testingwith p-values.
Please no written by hand solution and no img 4c. (Quantitative variable) Set up a T-distribution hypothesis test (StatCrunch T- stats -> One Sample). Copy and paste your results from StatCrunch into the write up. Explain the results (reject ?0 or fail to reject ?0) at the ?=0.05 significance level and at the ?=0.01 significance level. It is ok if this is the same question you used to construct the T-distribution confidence interval, if you don’t have enough quantitative questions in your survey to use a different question. Example hypothesis tests are in Chapter 7. Is the average mean of age for women higher than 0.05 and 0.01?
State the null and alternative hypotheses for the statistical test described below. Your answer should be an expression composed of symbols: =,≠,<,>,μ,μ1,μ2,p,p1,p2,0.3,ρ,p^,p^1,p^2,r.Testing to see if there is evidence that a proportion is greater than 0.3. H0: vs Ha:
