A sample of 1700 computer chips revealed that 63% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature claimed that over 60% do not fail in the first 1000 hours of their use. Is there sufficient evidence at the 0.02 level to support the company's claim?

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
