Saul decides to use the IQR to measure the spread of the data. Saul calculates the IQR of the data set to be 27 Saul asks Jasmine to check his work. Saul coples the data in numerical order from least to greatest for Jasmine.

25, 30, 50, 50, 50, 50, 56, n., 250

What is the value of n that will make the IQR of the data set equal to 27

Estimate the area under the curve f(x) = 16 - x^2 from x = 0 to x = 3 by using three inscribed (under the curve) rectangles. answer to the nearest integer.

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?
