You are conducting a study to see if the accuracy rate for fingerprint identification is significantly differentfrom 0.1. You use a significance level of a = 0.002.Ho:p = 0.1H1:p + 0.1You obtain a sample of size n = 704 in which there are 45 successes.What is the p-value for this sample? (Report answer accurate to four decimal places.)p-value = 0.1The p-value is...O less than (or equal to) agreater than aThis p-value leads to a decision to...O reject the nullaccept the nullOfail to reject the nullAs such, the final conclusion is that...O There is sufficient evidence to warrant rejection of the claim that the accuracy rate for fingerprintidentification is different from 0.1.O There is not sufficient evidence to warrant rejection of the claim that the accuracy rate forfingerprint identification is different from 0.1.The sample data support the claim that the accuracy rate for fingerprint identification is differentfrom 0.1.There is not sufficient sample evidence to support the claim that the accuracy rate for fingerprintidentification is different from 0.1.

1.12 To collect data in an introductory statistics course, I gave the students a questionnaire. One question asked whether the student was a vegetarian. Of 25 students, 0 answered study of 100 women suffering from excessive menstrual bleeding considers yes. They were not a random sample, but use these data to illustrate inference for a proportion. Let π denote the population proportion who would say yes. Consider H0: π = 0.50 and Ha: π ̸= 0.50. What happens when you conduct the Wald test, which uses the estimated standard error in the z test statistic? Find the 95% Wald confidence interval (1.3) for π. Is it believable? Conduct the score test, which uses the null standard error in the z test statistic. Report and interpret the P -value. Verify that the 95% score confidence interval equals (0.0, 0.133). (This is similar to the interval (0.0, 0.137) obtained with a small-sample method of Section 1.4.3, inverting the binomial test with the mid P -value.)
