Use MINITAB to answer the following: You just found out that you have been kicked out of your apartment (through no fault of your own!) and need to find a new place to live. Suppose monthly rent for an individual is a normally distributed random variable with a mean of 334 dollars and a standard deviation of 22 dollars. What is the probability that you will find an apartment that costs less than 275 dollars per month. A. 0.233529 B. 0.996339 C. 0.766471 D. 0.001350 E. 0.938882 F. 0.003661 G. 0.061118 H. 0.998650 Go to Calc > Probability Distributions > Normal. Select "Cumulative Probability" and enter 334 for the Mean and 22 for the Standard Deviation. Select "Input Constant" and enter 275. Click OK and the answer is 0.003661 Points Earned: 1/1 Correct Answer: F Your Response: F 2.

Suppose monthly rent for an individual is a normally distributed random variable with a mean of 334 dollars and a standard deviation of 22 dollars. What is the probability that you will find an apartment that costs more than 300 dollars per month. A. 0.766471 B. 0.061118 C. 0.998650 D. 0.996339 E. 0.003661 F. 0.001350 G. 0.938882 H. 0.233529

Go to Calc > Probability Distributions > Normal. Select "Cumulative Probability" and enter 334 for the Mean and 22 for the Standard Deviation. Select "Input Constant" and enter 300. Click OK and, since we want more than subtract 1 - this probability to get the answer 0.938882 Points Earned: 1/1 Correct Answer: G Your Response: G 3. For a normal random variable (Using Table A1 ), the probability of an observation being more than one standard deviation above the mean is: A. 0.1587 B. 0.8413 C. 0.6826 D. 0.3413 For a normal random variable (Using Table A1 ), the total probability above the mean is 0.5 (and below the mean as well). From the Empirical Rule we know that 68% of the observations fall with 1 standard deviation of the mean. So, 34% needs to be added to 50%, to find the cumulative
