Flag question: Question 2
Question 22 pts
Assume that the population for Age is normally distributed, even if the sample is not. Use the ATUS sample variable Age. What is the probability that any person in the sample is 20 years old or below? Type your answer as a probability or as a percentage (without the % sign).
NOTE: Do not calculate probability on a pivot table! You will need to calculate probability on the raw data.
Flag question: Question 3
Question 32 pts
Assume that the population for Age is normally distributed, even if the sample is not. Use the ATUS sample variable Age. What is the probability that any person in the sample is 65 years old or older? Type your answer as a probability or as a percentage (without the % sign).
Flag question: Question 4
Question 42 pts
Use the data dictionary to find the variable that measures how many hours the respondent usually works per week. Assume a normal probability distribution for the population. Ignoring any non-responses and responses of hours that may vary, what is the probability that any person in the sample usually works 20 hours or less. Type your answer as a probability or as a percentage (without the % sign).
NOTE: Using a filter and then calculating the probability from the filtered data will NOT effectively remove the filtered cases from the probability calculation. It will still calculate the probability from the full variable. I would suggest trying a different method for ignoring specific cases.
Flag question: Question 5
Question 52 pts
Use the data dictionary to find the variable that measures how many hours the respondent usually works per week (same variable as above). Assume a normal probability distribution for the population. Ignoring any non-responses and responses of hours that may vary, what is the probability that any person in the sample usually works between 30 and 40 hours? Type your answer as a probability or as a percentage (without the % sign).
NOTE: Using a filter and then calculating the probability from the filtered data will NOT effectively remove the filtered cases from the probability calculation. It will still calculate the probability from the full variable. I would suggest trying a different method for
