Kilometers Traveled for Work 12 10 18 3 4 28 5 32 26 10 41 85 1 7 8 5 10 15 ● A random sample of 80 tires showed that the mean mileage per tire was 41,700 mi, with a standard deviation of 4300 mi. a. Determine the z-score, to the nearest hundredth, for a tire that provided 46,300 mi of wear. b. The z-score for one tire was -2.44. What mileage did this tire provide? Round your result to the nearest hundred miles. E. Solve the following problems. The length of human pregnancies from conception to birth varies according to a distribution that is approximately normal, with a mean of 266 days and a standard deviation of 16 days. Draw a normal curve for this distribution on which the mean and standard deviation are correctly located. The concentration of the active ingredient in capsules of a prescription painkiller varies according to a normal distribution with µ = 10% and o = 0.2%. a. What is the median concentration? Explain your answer. b. What interval of concentrations covers the middle 95 percent of all the capsules? c. What interval covers the middle half of all capsules?
