(a) two-tailed test, level of Significance = .01, df = 28                    (b) one-tailed test, lower tail critical, level of significance = .05, df = 16     (c) one-tailed test, upper tail critical, level of significance = .01, df = 8

A survey of 61,646 people included several questions about office relationships. Of the respondents, 26.2% reported that bosses scream at employees. Use a 0.01 significance level to test the claim that more than 1/4 of people say that bosses scream at employees. How is the conclusion affected after learning that the survey is an online survey in which Internet users chose whether to respond? ldentify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hvnothesis, and final conclusion that addresses the original claim, Use the P-value method. Use the normal distribution as an annroximation of the binomial distribution. Hip>0.75 H;: p 0.75 The test statistic is z= (Round to two decimal places as needed.)

What would be the actual significance level (alpha) if 4 (four) group means were tested usingindependent pairwise t‐tests, each with a 95% confidence level?

(a) What is a sample, i.e. test, statistic? (b) Why do we compare a test statistic to the critical value(s) in a hypothesis test?

A random sample of n1 = 299 voters registered in the state of California showed that 140 voted in the last general election. A random sample of n2 = 220registered voters in the state of Colorado showed that 130 voted in the most recent general election. Do these data indicate that the population proportion of voter turnout in Colorado is higher than that in California? Use a 10% level of significance. What is the level of significance? What is the value of the sample test statistic? (Test the difference p1 − p2. Do not use rounded values. Round your final answer to two decimal places.) Find (or estimate) the P-value. (Round your answer to four decimal places.)

I need the test static, critical value , null & alternative hypothesis , conclusion & also probably p value Thankyou so much I need help kn working these out.

I need help finding the test statistic, p value, whether to reject or fail to reject and do the results support the belief in the problem. Thanks in advance for your help

Report an appropriate hypothesis test and use a 5% significance level. The alternative hypothesis for the One-way Anova F-test would be Group of answer choices Ha: Density affects firing temperature. Ha: Firing temperature affects density. Ha: Firing temperature does not affect density. Ha: Density does not affect firing temperature.

A survey of 61,647 people included several questions about office relationships. Of the​ respondents,27.3​% reported that bosses scream at employees. Use a 0.05 significance level to test the claim that more than 1/5 of people say that bosses scream at employees. How is the conclusion affected after learning that the survey is an online survey in which Internet users chose whether to respond? Identify the null​ hypothesis, alternative​ hypothesis, test​ statistic, P-value, conclusion about the null​ hypothesis, and final conclusion that addresses the original claim. Use the normal distribution as an approximation of the binomial distribution. Identify the null and alternative hypotheses. Choose the correct answer below.   A. H0​:p=0.2 H1​:p<0.2   B. H0​:p=0.2 H1​:p>0.2   C. H0​:p=0.2 H1​:p≠0.2   D. H0​: p=0.8 H1​: p<0.8   E. H0​: p=0.8 H1​: p≠0.8   F. H0​: p=0.8 H1​: p> 0.8   The test statistic is z= (Round to two decimal…
