A data set includes data from 400 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 2.3 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. Click the icon to view the display from technology. What are the null and alternative hypotheses? A. Ho: µ = 2.3 miles H1: µ< 2.3 miles B. Ho: µ = 2.3 miles H1: µ> 2.3 miles C. Ho: µ< 2.3 miles H1: µ= 2.3 miles D. Ho: µ = 2.3 miles H1: µ#2.3 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.

Past studies have indicated that the percentage of smokers was estimated to be about 34%. Given the new smoking cessation programs that have been implemented, you now believe that the percentage of smokers has reduced. You randomly surveyed 1708 people and found that 544 smoke. Use a 0.05 significance level to test the claim that the percentage of smokers has reduced.a) Identify the null and alternative hypotheses?H0H0:               H1H1:               b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? left-tailed right-tailed two-tailed c) Identify the appropriate significance level.d) Calculate your test statistic (Use ˆpp^ rounded to 4 decimal places). Write the result below, and round your test statistic to 4 decimal places.e) Calculate your p-value. Write the result below, rounded to four decimal places.f) Do you reject the null hypothesis? We reject the null hypothesis, since the p-value is less than the significance level. We reject the…

An online poll​ asked: "Do you believe the Loch Ness monster​ exists?" Among 22,007 ​responses, 67​% were​ "yes." Use a 0.05 significance level to test the claim that most people believe that the Loch Ness monster exists. How is the conclusion affected by the fact that Internet users who saw the question could decide whether to​respond? Find test statistic  Identify p value  Identify conclusion

Provide a significance level and explain how the confidence levels, C, are different for one and two tail tests. Provide pictures (with areas labeled) to support each C.
