Suppose you own ABC Tire manufactures. One particular tire lifespan is follows a normal distribution with a mean of 63,000 miles and a standard deviation of 4,350 miles. For questions 2-5 you MUST show your work - do NOT use statcrunch - use the tables, only values from the tables will be accepted. Each problem is worth 4 points 1. Insert the mean and 3 standard deviations in each directions on the horizontal axis of the normal curve below 29950 59300 58650 63000 Ex50 71730 760 50 2. What proportion of the tires will last at least 65,000 miles? P(X>65,000) P ( X765600)= 32 170% 65000 - 63000 4350 3. What is the probability that a randomly selected tire lasts between 60,000 and 70,000 miles? P( 60,000
