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 59 of 100 individuals prefer Brand A. Complete parts a through c.

When is a researcher at risk of making a Type II error? Group of answer choices: whenever H0 is rejected whenever H1 is rejected whenever H0 fails to be rejected The risk of a Type II error is independent of the decision from a hypothesis test.
Suppose an engineering firm is asked to check the safety of a dam. A) What kind of mistake would be made if the Ho (null hypothesis) that the dam is safe is wrongly rejected? B) What kind of mistake would be made if the Ho that the dam is safe is wrongly accepted?
A physician wants to test two blood glucose meters to see if there is any differences in measurements. To do this, he measures the glucose in blood samples taken from several randomly selected patients with both meters. Identify the null and alternative hypotheses for a hypothesis test, where each difference is calculated by subtracting the measurement on the second meter from the measurement on the first meter. A. H0:μd=0 Ha:μd>0 B. H0:μd=0 Ha:μd≠0 C. H0:μd=0 Ha:μd<0 D. H0:μd≠0 Ha:μd=0
The bottled beverage industry will use robots to fill drinks in bottles containing 1000 ml. There are 2 robot companies (A and B) that offer the industry. Beverage industry managers want the number of drinks that are filled into bottles not to be spilled. Robots are selected that produce the least spillage. To select the robot to be used, experiments were carried out on both robots and observed the amount of drink that spilled from each bottle. If µ1 = the average spill from robot A, µ2 = the average from robot B, then the hypothesis that can be tested from the data:) Ho: µ1- µ2 < 0 dan Ha: µ1- µ2 >= 0 (other) Ho: µ1- µ2 <= 0 dan Ha: µ1- µ2 > 0 Ho: µ1- µ2 = 0 dan Ha: µ1- µ2 not equal to 0

As a result of dog breeding for certain physical traits, many dog breeds have changed in the last 100 years. A dog breeder wants to measure the effects of breeding on the face length of the boxer breed using a hypothesis test. Suppose that the dog breeder has face length measurements (in inches) from a random sample of 40 female boxer dogs taken in 1915 and a random sample of 40 female boxer dogs taken in 2015. Which type of hypothesis test should the breeder use? Reference: Elegans, C. 100 Years of Breed Improvement. 2012. Dog Behavior Science.
