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 2. What proportion of the tires will last at least 65,000 miles? P(X>65,000) 3. What is the probability that a randomly selected tire lasts between 60,000 and 70,000 miles? P( 60,000
