Analysis of Heart Rate For fun a medical school professor once made a class of med students jump up and down for 1 minute and then measure their heart rate. Below are the values that were recorded:

136 144 99 145 135 125 115 127 124 101 100 103 130 119 121 123 116 115 126 114 125 125 116 137 152

Using StatCrunch - report back to the class the mean, median, and std deviation for the data

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.
