Re: rev HP17BII - stat problems and/or 42SX Message #5 Posted by Jose Sanchez on 11 Aug 2005, 6:46 p.m., in response to message #1 by Jose Sanchez
The 8.85 is the result derived from the TI83 or TI BA II PLUS.
The reason of my question is because the class and book are offering explanation with the TI "calculators". Indeed I get the 9.12 with the HP, but if my answers is distint from the others.....
I will get an exponential grade drop !(don't want it to happen)
I do not want to go TI EITHER !!
What parameter is not being accounted for ?
The answer 8.85 ..... Sum(data) = 230 {32,41,47,53,54}
Sum x^2 = 10,972
Sum X = 30
S=1/n *(sqrroot(n(sumx^2) -(SumX)^2)
Any inputs?
