ONLY USE MINITAB LAB AND SHOW STEPS OF HOW TO GET THERE> IF YOU AREN"T USING MINITAB LEAVE IT TO SOMEONE ELSE.

Next, we want to look at the average balance. We wish to have an average less than $525.

  1. Calculate a 99% confidence interval for the averagebalance. Interpret the result.
  2. Perform a hypothesis test using the previous information (1% level of significance). State the hypothesis. Calculate test statistic and p-value. Draw the appropriate conclusion.
  3. Suppose the overall averagebalancefor all individuals is 500. What, if any, type of error occurred?

Furthermore, we want to look at the difference between the average limit between students and nonstudents, namely if the average limit is different between students and nonstudents.

  1. Calculate a 95% confidence interval for the difference between the average limit by student status. Interpret the result.
  2. Perform a hypothesis test using the previous information (5% level of significance). State the hypothesis. Calculate test statistic and p-value. Draw the appropriate conclusion.
  3. Construct an appropriate graph to compare the limit for students and nonstudents. Describe the shape, location, and spread.

Lastly, we want to look at the average difference money left to spend before reaching the limit (limit - balance). We wish to have an average difference greater than $4000.

  1. Calculate a 95% confidence interval for the average difference. Interpret the result.
  2. Perform a hypothesis test using the previous information (5% level of significance). State the hypothesis. Calculate test statistic and p-value. Draw the appropriate conclusion.
