Question 6 3 pts A hypothesis test is used to prevent a machine from under or overfilling bottles of soda. On the basis of a sample, the hypothesis is rejected and the machine is shut down for inspection. An examination reveals there is nothing wrong with the filling machine. From a statistical point of view: O A Type 1 Error was made O A correct decision was made O A Type II Error was made O A Type I and...

A hypothesis test is used to prevent a machine from overfilling or under filling bottles of soda. On the basis of a sample, the hypothesis is rejected and the machine is shut down for inspection. A thorough examination reveals there is nothing wrong with the filling machine. From a statistical point of view: A Type II error was made A correct decision was made A Type I and Type II error was made A Type I error was made

2. A sports analogy for hypothesis tests Aa Aa E In recent years, professional sports have incorporated the use of instant replay in order to dispute questionable calls by the referees. For example, in the National Basketball Association (NBA) a head coach is allowed to challenge the referees' decision on whether a shot was made before time expired in the game. In order for the referees to reverse their original decision, the instant replay must...

Question 25 3 pts Suppose that the null hypothesis is that the medical treatment is not effective. Suppose that the medical treatment is truly effective, but a researcher does not reject the null hypothesis at the 5-percent level of significance. This researcher o is guilty of a post hoc ergo propter hoc fallacy. o has conducted a test with high statistical power. o has made a Type 1 error. o has made a Type 2 error. Question 26 3 pts...

A steel factory produces iron rods that are supposed to be 36 inches long. The machine that makes these rods does not produce each rod exactly 36 inches long. The lengths of these rods vary slightly. It is known that when the machine is working properly, the mean length of the rods is 36 inches. According to design, the standard deviation of the lengths of all rods produced on this machine is always equal to .05 inches. The quality control...
