The director of research and development is testing a new drug. She wants to know if there is evidence at the 0.05 level that the drug stays in the system for more than 352 minutes. For a sample of 54 patients the mean time the drug stayed in the system was 360 minutes. Assume the population standard deviation is 25. Find the p-value of the test statistic
bout 4% of the population has a particular genetic mutation. 300 people are randomly selected.Find the standard deviation for the number of people with the genetic mutation in such groups of 300. (Remember that standard deviation should be rounded to one more decimal place than the raw data, in this case 1 decimal place is necessary.)

A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 127.1-cm and a standard deviation of 1.6-cm. For shipment, 6 steel rods are bundled together. Find P17, which is the average length separating the smallest 17% bundles from the largest 83% bundles. P17 = |-cm Enter your answer as a number accurate to 2 decimal place.
