You've been assigned to do some hypothesis testing on the color of cars parked in the TCC parking lots. Your hypothesis testing will be based on using a proportion. Your think that the proportion of cars parked in the TCC parking lots are statistically the same as found throughout the world. Your instructions are to review 30 adjacent cars and determine the number of cars that are the color you were assigned.
You have been assigned red color cars. Dupont estimates that the word-wide average of red cars is 8%.
You counted your cars and found that there were 5 red cars in your sample.
Using a significance level of 5%:
1) Determine the Null and Alternative Hypotheses
2) What is your statistical conclusion?
3) What is your business decision/conclusion?

Color Blindness in Men and Women: In a study of red/green color blindness, 500 men and 2100 women are randomly selected and tested. Among the men, 45 have a red/green color blindness. Among the women, 6 have a red/green color blindness. Is there sufficient evidence to support the claim that men have a higher rate of red/green color blindness that women? Conduct the appropriate test at the alpha =.01 level. Is there one or two populations in this problem? Is...
You have been assigned to test the hypothesis that the average number of cars waiting in line during the early morning differs between Starbucks, PJ’s, and Aura Coffee. The following data show the number of cars in line during randomly selected times in the early morning at all three coffee shops: Number of cars waiting in line Coffee shop Time Starbucks PJ’s Aura Coffee 7:00 9 8 5 7:30 12 6 3 8:00 8 5 2 8:30 6 2 3...
You work in a very large metropolitan police department and have been assigned to a committee to select new patrol cars. Three models are in contention. The Dodge Charger The Chevrolet Tahoe The Ford Interceptor Your initial testing determines that all three models meet your department’s basic needs and that they are all comparably priced. So, the final decision is really based on the personal preference of the officers. You and the members of your committee send out a simple...
Hypothesis Testing O2 (when is 2. Cloud seeding has been studied for many decades as a weather modification procedure. The rainfall in a from 20 clouds that were selected at random and seeded with silver nitrate follows: 180 30.7 19.8 27.1 22.3 18.8 31.8 23.4 21.2 27.9 31.9 27.1 25.0 24.7 26.9 218 29.2 34.8 26.7 31.6 Write down the null and alternative hypotheses to test the claim that mean rainfall from seeded clouds exceeds 25 acre feet. a b....
Hypothesis Testing Example 7: Steps in Hypothesis Testing: A manufacturer claims that the thickness of the spearmint gum it produces is 7.5 one- hundredths of an inch. A quality control specialist regularly checks this claim. On one production run, he took a random sample of n= 10 pieces of gum and measured their thickness. The quality control specialist's hypotheses are: HO: 1. Step 1: State Hypotheses 2. Step 2: Select alpha, Draw Picture, Label Critical Values and Rejection Region(s) 3....
ESAND ABUSES 1 Uses Hypothesis Testing Hypothesis testing is important in many different fields because it gives a scientific procedure for assessing the validity of a claim about a population. Some of the concepts in hypothesis testing are intuitive, but some are not. For instance, the American Journal of Clinical Nutrition suggests that eating dark chocolate can help prevent heart disease. A random sample of healthy volunteers were assigned to eat 3.5 ounces of dark chocolate each day for 15...
Q1. Hypothesis testing using a Z test (14 points) A professor has been teaching introductory statistics for many years and the final exam performance (30 points total) has been very consistent from class to class and the scores have been normally distributed. Overall, the whole data base (i.e. population) of final exam scores has a mean (μ) of 20 points and a standard deviation (σ) of 5 points. Because 20 out of 30 is only about 67%, the professor would...
Can someone help me by answering #2 of these questions. Using the techniques described in sections 10.2 and 10.3 of the text, for each of these hypothesis testing problems, (a) state the null and alternative hypotheses, (b) determine the critical value(s), (c) calculate the test statistic, (d) decide whether or not to reject the null hypothesis, and (e) write a full conclusion in the context of the problem 1. A group of people were asked the question, "If you received...

1) A food distributor is being sued for racial discrimination because 12% of newly hired candidates are not white when 53% of all applicants were not white. You plan to use hypothesis testing to determine whether there is significant evidence that the company's hiring practices are discriminatory. Part A: State the null and alternative hypotheses for the significance test. (2 points) Part B: In the context of the problem, what would a Type I error be? A Type II error?...
