Multiple Choice

Use the following information for following questions .
A random sample of 100 cars was taken and data were recorded on the miles per gallon (mpg) in the city
and on the highway. The mean city mpg was 28 with a standard deviation of 9.2. The mean highway mpg
was 35 with a standard deviation of 8.6. The correlation coefficient between city mpg and highway mpg is
-Determine the correct value of the slope for the linear model that predicts highway mpg from city mpg and interpret it in context.

• A)The slope is 0.888.For every one mpg increase in city mpg, the highway mpg is predicted to increase by 0.888.
• B)The slope is 0.888.For every one mpg increase in highway mpg, the city mpg is predicted to increase by 0.888.
• C)The slope is 1.016.For every one mpg increase in city mpg, the highway mpg is predicted to increase by 1.016.
• D)The slope is 1.016.For every one mpg increase in highway mpg, the city mpg is predicted to increase by 1.016.

Definitions:

Contingency Reinforcement Schedule

A plan or method in operant conditioning by which a certain behavior is reinforced based on meeting specific conditions or criteria.

Differential Reinforcement Schedule

A schedule of reinforcement in which a specific number of behaviors must occur within a specified time in order for reinforcement to occur

Variable-Ratio Schedule

A reinforcement schedule in which a response is rewarded after an unpredictable number of responses, leading to a high and steady rate of responding because the exact number varies.

Fixed-Ratio Schedule

A type of reinforcement schedule where a response is reinforced only after a specified number of responses, leading to a high and steady rate of response.
