Question

9. Carboxy- hemoglobin is formed when hemoglobin is exposed to carbon monoxide.
Heavy smokers tend to have a high percentage of carboxyhemoglobin in their blood
(Reference: A Manual of Laboratory and Diagnostic Tests by F. Fischbach). Let x be a
random variable rep- resenting percentage of carboxyhemoglobin in the blood. For a
person who is a regular heavy smoker, x has a distribution that is approximately
normal. A random sample of n-12 blood tests given to a heavy smoker gave the
following results (percentage of carboxyhemoglobin in the blood):
9.1 9.5 10.2 9.8 11.3 12.2 11.6 10.3 8.9 9.7 13.4 9.9
Where = 10.49 and s = 1.36.
A long-term population mean u -10% is considered a health risk. However, a long-
term population mean above 10% is considered a clinical alert that the person may be
asymptomatic. We will investigate the claim: the data indicate that the population
mean percentage is higher than 10% for this patient? Use a = 0.05.
a. Find the test statistic.
b.
Find the critical value zo that defines the rejection region.
c. Would you support the claim? Why?
d. Use the given data to find a 99% confidence interval for u for this patient.

A travel agency wants to promote pleasure trips into space and wants to know which of the two commercial companies should they promote Virgin Galactic or Blue Origin? The one preferred by the customers will be the one they decide to promote. For this reason they take a random sample of 16 potential travelers, and they ask if they would prefer Virgin Galactic or Blue Origin. Let X be the number of travelers who preferred Virgin Galactic and let p=X/16 denote the corresponding proportion. Suppose that we want to show that Virgin Galactic is preferred to Blue Origin. Please formulate the null and alternative hypotheses and calculate the rejection region. Use α=0.05 Suppose that 11 out of 16 prefer Virgin Galactic and that α = 0.05, is this enough evidence to show that Virgin Galactic is preferred to Blue Origin? Perform the test and give your conclusion. Which company should they promote?
