Let C be a number such that P(χ2 > C) = 0.05for the χ2 distribution with 5 degrees of freedom. Which of the following is true? a) P(χ2 > 2C) > P(χ2 > C) ​​​​​
b) P(χ2 < –C) = P(χ2 > C)
c) P(χ2 > C) < 0.05 for the χ2 distribution with 10 degrees of freedom.
d) P(χ2 > (C + 2)) < 0.05
e) P(χ2 > C) = 0.05 regardless of the degrees of freedom for the distribution.

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?

The mass of a marine organism, in pounds, p years after it is born is given by the polynomial function r(p) = -4p2 + 300p. find the mass when p = 20 years.
