I have figured them all out except D
On average, commuters in Phoenix, Arizona, area requirem= 40.0 minutes to get to work. Assume thetimes to get to work are normallydistributed with astandard deviation of s= 10 minutes, and that Joe is anaverage Phoenix resident.
- What is the probability that on any given day Joe will requireover 45 minutes to get to work?
- What is the probability it will take Joeexactly40.0 minutes to get to work on anygiven day?
- Joe has just left home from lunch to attend a meeting with theCEO in 30 minutes. If the CEO routinely fires employeeswho are tardy for meetings, what is the probability the Joe willstill be employed tomorrow?
- Joe leaves home for work at exactly the sametime. His work starts at 8:00 AM sharp. Dueto traffic jams during the morning rush hour, Joe was tardy forwork on 38.2% of the time. What time does Joe leave homefor work every morning? Briefly explain your train ofthought in arriving to the answer.
