2. A student asks her teacher "What is the probability that it will take you exactly 20 minutes to walk to school in the morning?" What will be the teacher's reply? What is a better question to ask? Explain by referring to concepts that we discussed in this unit. 3. Describe how calculating probability for continuous random variables is different than calculating probability for discrete random variables. Explain using examples discussed in the activity and ideas discussed in this unit. 4. The heights of players in Major League Baseball are normally distributed and have a minimum of 5.5 feet and maximum of 6.83 feet. Someone in our class explains that the standard deviation must be less than 1/4 of the difference between the max and the min. To what extent do you agree? Totally agree, somewhat agree, disagree. Defend your decision by including a sketch of a normal curve and referring to properties of the normally distributed data discussed in this unit
