Step 1(a) Can a normal distribution be used for the p distribution? Explain.Recall that to test a proportion, p, assuming all requirements are met, the z values will be calculated using thefollowing formula, where r is the number of successes, n is the number of trials, p = - is the sample statistic,p is the population probability of success, and q = 1 - p represents the population probability of failure.p - Pz =paIn order to use the normal distribution to estimate the p distribution, the number of trials n should besufficiently large so that both np > 5 and nq > 5. We will first check that these requirements are met.We have a random sample of 20 binomial trials resulting in 7 successes and we wish to test the claim that thepopulation proportion of successes does not equal 0.50 using a significance level of 0.05. Therefore, we candefine n, p, and q as follows.n = 20p =q = 1-p =

(a) Let p denotes the population proportion of successes. The sample size is 20, and population…

Question Help ▼ A car company says that the mean gas mileage for its luxury sedan is at least 21 miles per gallon (mpg). You believe the claim is incorrect and find that a random sample of 7 cars has a mean gas mileage of 20 mpg and a standard deviation of 3 mpg. At a= 0.025, test the company's claim.
