An experienced farmer says that the standard deviation for the number of lettuce plants that can grow in one acre is at most 59 plants. The soils department comes to
the farm and randomly selects 15 acres and finds that the number of lettuce plants
per acre has a standard deviation of 62 plants. Is there enough evidence to reject the
farmer's claim at a 10% level of significance? Make sure to state the hypotheses, p
value with interpretation and conclusion.

Which of the following is the inverse of y = 3∧x y = 1/3∧x y = ㏒3x y = (1/3) ∧x y = ㏒ 1/3∧x

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?
