Someone in our class explains that the standard deviation must be less than of the difference between the max and the min. To what extent do you agree? Totally agree, somewhat agree, disagree. Defend your decision by referring to properties of the normally distributed data discussed in this unit.
3. The length of time of full-length movies is approximately normally distributed with a mean of 1.9 hours and standard deviation of 0.3 hours. Based on this scenario, explain what a Z-Score is.
