Agroup of 20 students are being asked to report the number of pets they keep in their house the results are 0,0,0,0,0,1,1,1,1,1,1,1,1,2,2,3,4,4 ,4,21

mean is 2.4
standard deviation is 4.47
quartile 1 is 0.5
median is 1
quartile 3 is 2.5

after being told that they should not count any fish in the report, the value of 3 becomes a 2 and the value of 21 becomes 1. would these changes affect the median, mean, standard deviation or inter quartile range ? if so would each measure decrease or increase from their original values?

Suppose i pick a jelly bean at random from a box containing one red and eleven blue ones. i record the color and put the jelly bean back in the box. if i do this three times, what is the probability of getting a blue jelly bean each time? (round your answer to three decimal places.)

Find the center of the circle that can be circumscribed about efg with e(4,4) f(4,2) g(8,2)

Suppose we have a set of small wooden blocks showing the 26 letters of the english alphabet, one letter per block. (think of scrabble tiles.) our set includes 10 copies of each letter. we place them into a bag and draw out one block at a time. (a) if we line up the letters on a rack as we draw them, how different ways coukl we fill a rack of 5 letters? (b) now suppose we just toss our chosen blocks into a pile, and whenever we draw a letter we already have, we put it back in the bag and draw again. how many different piles of 5 blocks could result? possible? piles will contain at least one repeated letter? (c) if we draw out 5 blocks wit hout looking at them, how many different piles are (d) if we draw out 5 blocks without looking at them, how many of the possible 2. (4) consider the following formula. 12 give two different proofs, one using the factorial formulas and the other combina torial.
