I'm having trouble with two questions in my statistics class. If someone could explain these to me I would appreciate it!

Question 1.

Consider a drug testing company that provides a test for marijuana usage. Among 287 tested subjects, results from 29 subjects were wrong (either a false positive or a false negative). Use a 0.05 significance level to test the claim that less than 10% of the test results are wrong.

  • Identify the null and alternative hypotheses for this test.
  • Identify the test statistic for this hypothesis test.
  • Identify the P-value for this hypothesis test.
  • Identify the conclusion for this hypothesis test. (Fail to reject, reject)

Question 2.

In a study of the accuracy of fast food drive-through orders, one restaurant had 37 orders that were not accurate among 337 orders observed. Use a 0.10 significance level to test the claim that the rate of inaccurate orders is equal to 10%. Does the accuracy rate appear to be acceptable?

  • Identify the null and alternative hypotheses for this test.
  • Identify the test statistic for this hypothesis test.
  • Identify the P-value for this hypothesis test.
  • Identify the conclusion for this hypothesis test. (Fail to reject, reject)
  • Does the accuracy rate appear to be acceptable?
