Question 2 options: 1) 0.3552 2) We do not have enough information to calculate the value. 3) 0.1647 4) 0.8353 5) 0.6448 Question 3 (1 point) Suppose that the distribution of income in a certain tax bracket is approximately normal with a mean of $53,114.38 and a standard deviation of $1,350.89. Approximately 2.87% of households had an income greater than what dollar amount? Question 3 options: 1) 3,414,662 2) 3,520,891 3) 50,547.35 4) We do not have enough information to calculate the value. 5) 55,681.42 Question 4 (1 point) Suppose that the distribution of income in a certain tax bracket is approximately normal with a mean of $52,585.33 and a standard deviation of $1,112.988.

Would it be unusual for a commute time to be between 27 and 27.9 minutes? Question 5 options: 1) A value in this interval is not unusual. 2) A value in this interval is borderline unusual. 3) It is impossible for a value in this interval to occur with this distribution of data. 4) A value in this interval is unusual. 5) We do not have enough information to determine if a value in this interval is unusual.

These measurements were found to be normally distributed with mean of 81.775 mph and standard deviation of 3.4282 mph. Would it be unusual to record a value between 80.49 and 82.81 mph? Question 6 options: 1) It is impossible for a value in this interval to occur with this distribution of data. 2) A value in this interval is unusual. 3) A value in this interval is borderline unusual. 4) We do not have enough information to determine if a value in this interval is unusual. 5) A value in this interval is not unusual
