A political candidate has asked his/her assistant to conduct a poll to determine the percentage of people in the community that supports him/her. If the candidate wants a 6% margin of error at a 95% confidence level, what size of sample is needed? Be sure to round accordingly. The candidate would need to survey people in the community in order to be within a 6% margin of error at a 95% confidence level.

In a recent study, researchers found that 40 out of 250 boys aged 7-13 were overweight or obese. On the basis of this study can we conclude that more than 15% of the boys aged 7-13 in the sampled population are overweight or obese? Use a 5% level of significance. 1) the appropriate null and alternative hypotheses; 2) the appropriate test; 3) the decision rule; 4) the calculation of the test statistic, and 5) your conclusion including a comparison to alpha or the critical value.

Trials in an experiment with a polygraph include 96 results that include 24 cases of wrong results and 72 cases of correct results. Use a 0.05 significance level to test the claim that such polygraph results are correct lass than 80% of the time. Identify the null hypotheses, alternative hypotheses,test statistics, P-value, conclusion about the null hypothesis and final conclusion that adresses the original claim. I'm use the P- value method. use the normal distribution as an approximation of the binomial distribution.
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 2.5 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. Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A. Ho: µ=2.5 miles O B. Ho: H= 2.5 miles H,: µ#2.5 miles H,: µ> 2.5 miles Ο C.
