In a random sample of males, it was found that 223 write with their right hands and 21 do not. In a random sample of females, it was found that 452 write with their right hands and 67 do not. We want to use a 0.01 significance level to test the claim that the rate of right-handedness among males is more than that among females. If we let: Let μ1 be the population mean number of males are right-handedness, and μ2 be the population mean number of females are right-handedness. Let p1 be the population proportion of males are right-handedness, and p2 be the population proportion of females are right-handedness. Round to three decimal places if necessary. a) Null hypothesis H0 : . Alternate hypothesis H1 : . b) Type of test: -tailed test. c) significance level: α = d) Test statistic: e) Compute p-value of the test statistic. f) Decision: g) Write conclusion
