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. Approximately 43.65% of households had an income greater than what dollar amount? Question 4 options: 1) 250,597.2 2) 52,763.24 3) We do not have enough information to calculate the value. 4) 52,407.42 5) 145,426.5

Question 5 (1 point) Suppose that one-way commute times in a particular city are normally distributed with a mean of 24.88 minutes and a standard deviation of 2.495 minutes. 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.

Question 6 (1 point) Measurements were recorded for the slapshot speed of 100 minor-league hockey players. 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
