In a program designed to help patients stop smoking, 195 patients were given sustained care, and 83.1% of them were no longer smoking after one month. Use a 0.05significance level to test the claim that 78% of patients stop smoking when given sustained care. Use the P-value method. Use the normal distribution as anapproximation to the binomial distribution.Identify the null and alternative hypotheses.Но: р0.81H1:P0.81(Choose answer: a for =, b for > , c for < , d for +)Identify the test statistic:(Round to two decimal places)Identify the P valuep value =(Round to three decimal places.)Conclusion:(Fail to reject or Reject )

use a hypothesis test to determine if the proportions are statistically different. A recent survey showed that in a sample of 100 elementary school teachers, 15 were single. In a sample of 180high school teachers, 36 were single. Is the proportion of high school teachers who were single greater than theproportion of elementary teachers who were single? Use ΅ = 0.01.

K Census data for a certain county show that 17% of the adult residents are Hispanic. Suppose 74 people are called for jury duty and only 10 of them are Hispanic. Does this apparent underrepresentation of Hispanics call into question the fairness of the jury selection system? Explain.. Write appropriate hypotheses.

Ramos has a spinning wheel. The Spining wheel has 18 blue numbers 18 white numbers and 2 yellow numbers the table provided shows the frequency with which the ball landed on each color in 200 trials. color blue frequency 18 white frequency 18 yellow frequency 2 . At the 5% significance level do the data suggest that the wheel is out of balance?you will need to compute the expected counts to do your calculations remember that the expected counts can be computed with the formula E = np, where n is the number of trials and P is the probability of each color.
