RE: Normal Dist for 2 variable statistics on WP 34S
Entering average monthly daily high and low temperatures for Laredo. They do not approximate a normal distribution, but will serve to illustrate. 46 enter 68 summation, 50 enter 73 summation, 56 enter 81 summation, 64 enter 88 summation, 71 enter 95 summation, 75 enter 99 summation, 76 enter 100 summation, 76 enter 100 summation, 72 enter 94 summation, 65 enter 88 summation, 54 enter 77 summation, 46 enter 68 summation.
Press Xbar, get 85.92 in X display line, 62.75 in y display line. If I type 66 in the command line, go to probability menu, and choose Norml, I get .05 which is correct for the X values that I have entered (high temperatures)...correctly showing that 66 is on the lower end of the cumulative distribution. My question is, how do I switch the X and Y summations so that I can type in 66, go to probability menu, execute Norml, and get .61, showing that for low of the days, I'm in the meat of the distribution.
