5. Possible outcomes of a hypothesis test The following table depicts the four possible outcomes of a hypothesis test: The researcher makes a correct decision [either by correctly rejecting the null hypothesis (H₀) or correctly not rejecting the null hypothesis], makes a Type I error, or makes a Type II error. In each of the following boxes, select the description that matches the outcome. Decision Truth H₀ False H₀ True Reject H₀ Outcome A Outcome B Do not reject H₀ Outcome C Outcome D The probability of a Type I error is , and the probability of a Type II error is .
A manufacture of flash drives for data storage operates a production facility that runs on three 8-hour shifts per day. The following contingency table shows the number of flash drives that were defective and not defective from each shift. Shift Defective Not Defective 7AM – 3PM 7 113 3PM – 11PM 10 90 11PM – 7AM 4 76 Perform a hypothesis test to determine if the quality of the flash drive production and the production shift are independent variables using a = 0.05.
Español Try Again Your answer is incorrect. The proportion of residents in a community who recycle has traditionally been 65%. A policy maker claims that the proportion is less than 65 % now that one of the recycling centers has been relocated, and the policy maker wishses to carry out a hypothesis test. State the null hypothesis H, and the alternative hypothesis H, that the policy maker would use for this test. Ho: 0.65 Aa H: 0.65 S O
The market shares in 2012 of four (4) television companies, A, B, C and D are listed below. A survey was carried out in 2017 on 200 television buyers and the distribution of buyers to A, B, C and D are also listed in the last column. Company Market Share in 2012 Number of buyer in 2017 A 0.4 70 B 0.32 60 C 0.24 54 D 0.04 16 (a) Specify the competing hypotheses to test whether the market shares have changed since 2012. (b) Calculate the value of the test statistics. (c) Use ? = 0.05 to determine if the market shares have changed since 2012.

A blind taste test is conducted to determine which of two colas, Brand A or Brand B, individuals prefer. Individuals are randomly asked to drink one of the two types of cola first, followed by the other cola, and then asked to disclose the drink they prefer. Results of the taste test indicate that 58 of 100 individuals prefer Brand A. Complete parts a through c. (a) Conduct a hypothesis test (preferably using technology) H0:p=p0 versus H1:p≠p0 for p0=0.47,0.48,0.49,...,0.67,0.68,0.69 at the α=0.05 level of significance. For which values of p0 do you not reject the null hypothesis? What do each of the values of p0 represent? Do not reject the null hypothesis for the values of p0 between _ and _,inclusively.
Discuss one of the following topics. Write a brief but complete essay (minimum 200 words) in which you answer one the following questions. Cite any sources that you use. (a) What is a null hypothesis, H0 ? Describe its importance.
You watch people exiting Dodgers stadium after a game and you write down the number of males and the number of females that exit the stadium past you during the 20 minutes that you spend watching. You assumed that there would be a perfectly equal number of males and females attending a Dodgers game, but you look at the number of males and females that you actually counted, and you see if you still think that is actually true. What kind of hypothesis test would allow you to do this? a. One-Factor, Independent-Measures ANOVA b. Two-Factor ANOVA c. Correlation/Regression d. Chi-Square Goodness of Fit
Which statement describes a Type II Error? Fail to reject the null hypothesis H0, when H0 is actually true Reject the null hypothesis H0, when H0 is actually true Fail to reject the null hypothesis H0, when H0H0 is false Reject the null hypothesis H0, when H0 is actually false
