How do the four schedules of reinforcement work?

Fixed-ratio schedule - reinforcement depends on a specific number of correct responses before reinforcement can be obtained. Like rewarding every fourth response. Variable-ratio schedule - reinforcement does not required a fixed or set number of responses before reinforcement can be obtained. Like slot machines in the casinos. Fixed-interval schedule - reinforcement in which a specific amount of time must elapse before a response will elicit reinforcement. Like studying feverishly the day before the test. Variable-interval schedule - reinforcement in which changing amounts of time must elapse before a response will abtain reinforcement.


TO ESTIMATE THE AVERAGE AGE OF STUDENTS A SAMPLE OF 50 PARTICIPANTS WAS OBTAINED, WITH A MEAN OF 16 AND A POPULATIONAL VARIATION OF 9, calculate:* POINT ESTIMATE OF THE MEANS* 95% AND 99% CONFIDENCE INTERVAL ESTIMATES FOR THE MEANS?

Point Estimate of the Mean: The point estimate of the mean is 16, since this is the sample mean. 95% Confidence Interval Estimate for the Mean: The 95% confidence interval estimate for the mean can be calculated using the following formula: Mean +/- Margin of Error = (16 +/- 1.96*(9/sqrt(50))) = 16 +/- 1.51 = 14.49 to 17.51 99% Confidence Interval Estimate for the Mean: The 99% confidence interval estimate for the mean can be calculated using the following formula: Mean +/- Margin of Error = (16 +/- 2.58*(9/sqrt(50))) = 16 +/- 2.13 = 13.87 to 18.13
