Suppose That You Wish to Compare the Mean Home Values

question 6

Multiple Choice

Suppose that you wish to compare the mean home values from three different regions. The Bonferroni-corrected intervals for all three comparisons are shown in the table. Assume an overall confidence level of 95%, that is, an individual confidence level of 98.33%. Choose the statement that is true about the differences among the three means. If none of the statements is true, then choose (d) . North East - North Central ($52,485, $78,875) North East - Far West (-$8,724, $14,547) Far West - North Central ($50,093, $75,443)

• A)The interval comparing North East to North Central does not capture 0; there is no significant difference in the mean home values between the North East and the North Central regions.
• B)The interval comparing Far West to North Central does not capture 0; there is no significant difference in the mean home values between the Far West and the North Central regions.
• C)The interval comparing North East to Far West captures 0; there is no significant difference in mean home values between the North East and the Far West regions.
• D)None of the statements is true.

Definitions:

Reinforcers

Stimuli, events, or conditions that increase the likelihood of a behavior being repeated.

Reinforcement

In operant conditioning, any event that strengthens the behavior it follows.

Successive Approximations

A method of shaping behavior by rewarding actions that are progressively closer to the desired behavior.

Shaping

The process of reinforcing closer and closer approximations to a desired behavior in order to teach a new behavior.
