Crime Doesn't Pay!... Unless It Does A new forger is in town and the police need to track them down. They want to know if the ink the new forger is using comes from a known supplier who uses a particular chemical in their ink. The police are highly confident that the mean chemical concentration in the ink from the known supplier is equal to 37 units. The police have collected 38 samples of ink from the new forger and measured the chemical concentration in each sample. Given the sample mean, = 36.99, sample size, n = 38, and the sample standard deviation, s =3.39 a) Define the quantity of interest: Let ? be the ? This is the "parameter" in the hypotheses below. b) Null value = c) Fill in the values for the hypotheses: chemical concentration in the ink of the new forger. Ho parameter ? null value vs HA parameter ? null value d) What is the test statistic: test statistic = e) What is the p-value associated with that statistic: p-value = f) What is the statistical decision using a = 0.07: O Fail to reject the null hypothesis O Accept the null hypothesis O Fail to reject the alternative hypothesis Reject the alternative hypothesis O Reject the null hypothesis Accept the alternative hypothesis g) Find the 93% confidence interval for the quantity of interest. 93% confidence interval is $ to
