Seminar 4 Statdisk Assignment (5 points total):
Name: Rob Morell
For the 3 problems assume a distribution with mean = 0 and a standard deviation = 1
Format for the assignment:
Part I: Manual Calculations
First show the manual calculations for each problem. I'll get them set up to help get you started.
1. Less than 2.34
First, we need to locate our z score in Table A2.
This will be on the left hand margin of the table. The
area numbers are in the body of the table. Our z score corresponds with _____ in our table.
The
probability of value less than 2.34 is 99.0358%.
2. Between 1 and 3
First, we need to locate our z scores in Table A2.
Our first z score of 1 corresponds to
beginning
in our
table, and our second z score of 3 corresponds to the
end
Now, we must subtract our first value from our
second value; therefore, .9987  .8413 = .1574
