The length in feet of a structural I-beam is normally distributed with a mean of 6 ft and a standard deviation of 1 inch. Quality control requirements demand a beam to be rejected if the length of the beam is more than 1 inch different from the mean. What percentage of the I-beams will be rejected?
The speed limit in a school zone is 40km/h. A survey of cars passing the school shows thattheir speeds are normally distributed with a mean of 37.5 km/h and a standard deviation of5.6km/h. What percent of cars passing the school are speeding?
Most water treatment facilities monitor the quality of their drinking water on an hourly basis. One variable measured is pH, which measures the degree of alkalinity or acidity in the water. A pH below 7.0 is acidic, one above 7.0 is alkaline, and a pH of 7.0 is neutral. One water-treatment plant has a target pH of 8.5. (Most try to maintain a slightly alkaline level) The mean and standard deviation of 1 hour’s test results based on 49 water samples at this plant are: = 8.42; s = 0.16 Does this sample provide sufficient evidence that the mean pH level in the water differs from 8.5? do in excel if needed
