IEA 01 PROBABILITY AND STATISTICAL METHODSInstruction to candidates:

1) Answer Any Five questions.2) Use of Statistical tables permitted3) Show the working steps clearly.

1a) The national highway traffic safety administration reported therelative speed (rounded to the nearest 5 Mps) of automobilesinvolved in accidents one year. The percentages at the differentspeeds were 12

20 Mph or less 2.0%

45 Mph or 50 Mph 16.5%

55 Mph 19.2%

60 or 65 Mph 2.2%

1. From these data can we conclude that it is quite safe todrive at high speeds? Why or why not?

4b) A trucking firm is suspicious of the claim that the average lifetime of certain tires is at least 28,000 miles. To check the claimthe firm puts 40 of these tires on its trucks, and gets a meanlife time of 27,463 miles, with a standard deviation of 1348miles, what can you conclude if the probability of a type I erroris to be at most 0.01? 8
