In the 19th century, most books quoted "blood heat" as 98 F, until a study published the mean (but not the variance) of a large sample as 36.88 °C. Subsequently, that mean was widely quoted as "37 C”. This translates to 98.6 F. (Wikipedia) In a recent study of 148 healthy men and women ages 18-40 years, participating in the Shigella Vaccine Trials at the University of Maryland Center for Vaccine Development, had oral temperatures measured 1-4 times daily for three consecutive days using an electronic digital thermometer. The mean observed oral temperature was 36.8 C which translates to 98.2 F, with a standard deviation of 0.62 F. (Altern Med Rev 2006;11(4):278-293) If you select a person at random from a population with body temperatures that are N(98.2,0.62)… 4. Use the empirical rule to determine the probability that the body temperature is larger than 99.44. Round to 4 decimal places

In a test for esp (extrasensory perception), a subject is told that cards only the experimenter can see contain either a star, a circle, a wave, or a square. as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. a subject who is just guessing has probability 0.25 of guessing correctly on each card. a. the count of correct guesses in 20 cards has a binomial distribution. what are n and p? b. what is the mean number of correct guesses in 20 cards for subjects who are just guessing? c. what is the probability of exactly 5 correct guesses in 20 cards if a subject is just guessing?
