In a one-way analysis of variance test in which the levels of the factor being analyzed are randomly selected from a large set of possible factors, the design is referred to as:
A) a fixed-effects design.
B) a random-effects design.
C) an undetermined results design.
D) a balanced design.
Q. 2If a decision maker wishes to reduce the chance of making a Type II error, one option is to increase the sample size.
Indicate whether the statement is true or false
Q. 3The primary application for the hypergeometric probability distribution is in situations where the sampling is done without replacement from a finite population.
Indicate whether the statement is true or false
Q. 4In conducting a one-way analysis of variance where the test statistic is less than the critical value, which of the following is correct?
A) Conclude that the means are not all the same and that that the Tukey-Kramer procedure should be conducted.
B) Conclude that the means are not all the same and that that the Tukey-Kramer procedure is not needed.
C) Conclude that all means are the same and that the Tukey-Kramer procedure should be conducted.
D) Conclude that all means are the same and there is no need to conduct the Tukey-Kramer procedure.
Q. 5Type II errors are typically greater for two-tailed hypothesis tests than for one-tailed tests.
Indicate whether the statement is true or false
Q. 6The makers of Crustfree Bread in Boston have a quality standard that allows for no more than 3 burned loaves per batch on average.
Assuming that the average of 3 per batch is being met, the standard deviation for the number of burned loaves in 4 batches is approximately 1.73 loaves. Indicate whether the statement is true or false
Q. 7If a decision maker is concerned that the chance of making a Type II error is too large, one option that will help reduce the risk is to reduce the significance level.
Indicate whether the statement is true or false
