In a recent court case, it was found that during a period of 11 years 896 people were selected forgrand jury duty and 35% of them were from the same ethnicity. Among the people eligible forgrand jury duty, 79.8% were of this ethnicity. Use a 0.05 significance level to test the claim that theselection process is biased against allowing this ethnicity to sit on the grand jury. Identify the nullhypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, andfinal conclusion that addresses the original claim. Use the P-value method and the normaldistribution as an approximation to the binomial distribution.Which of the following is the hypothesis test to be conducted?Ho: P0.798(choose a for = ; b for > ; c for < and d for +)H1: p0.798(choose a for = ;b for > ; c for < and d for 7)What is the test statistic?Z =(Round to two decimal places)What is the P value?(Round to three decimal places.)What is the conclusion on the null hypothesis?(Reject or Do not reject)

In a study of 420,098 cell phone users, 121 subjects developed cancer of the brain or nervous system. Test the claim of a somewhat common belief that such cancers are affected by cell phone use. That is, test the claim that cell phone users develop cancer of the brain or nervous system at a rate that is different from the rate of 0.0340% for people who do not use cell phones. Because this issue has such great importance, use a 0.001 significance level.

In one study of smokers who tried to quit smoking with nicotine patch therapy, 40 were smoking one year after treatment and 33 were not smoking one year after the treatment.
