The relative humidity, in percent, in the morning for the months of January through December in Boston follows: \(\begin{array}{llllll}68 & 67 & 69 & 69 & 71 & 73 \\ 74 & 76 & 79 & 77 & 74 & 70\end{array}\) Find the average and the median of these humidity readings.
Use the appropriate normal distributions to approximate the resulting binomial distributions. Bearings is the principal supplier of ball bearings for the Sperry Gyroscope Company. It has been determined that \(6 \%\) of the ball bearings shipped are rejected because they fail to meet tolerance requirements. What is the probability that a shipment of 200 ball bearings contains more than 10 rejects?
BLooD TYPES It is estimated that one third of the general population has blood type \(\mathrm{A}^{+}\). If a sample of nine people is selected at random, what is the probability that a. Exactly three of them have blood type \(\mathrm{A}^{+}\) ? b. At most three of them have blood type \(\mathrm{A}^{+}\) ?
Use the appropriate normal distributions to approximate the resulting binomial distributions. Colorado Mining and Mineral has 800 employees engaged in its mining operations. It has been estimated that the probability of a worker meeting with an accident during a 1-yr period is .1. What is the probability that more than 70 workers will meet with an accident during the 1 -yr period?
