7. Loaves of bread in a certain bakery are approximately normally distributed with a mean length of 32 centimeters and a standard deviation of 2 centimeters.
- If a loaf is 34 centimeters long, how many standard deviation(s) is it from the mean? Show all work. (2 points)
- If a loaf is 28 centimeters long, how many standard deviation(s) is it from the mean? Show all work. (2 points)
- What percentage of the loaves are expected to be between 30 to 34 centimeters in length? Explain. (2 points)
- What percentage of the loaves are expected to be between 28 to 36 centimeters in length? Explain. (2 points)
- If the baker found out that one of the loaves turned out to be 40 centimeters long, is that considered an outlier? Explain. (2 points)
