I am taking community college classes in statistics and I had a quiz last week. Counts for 20 points. I got the results today and I lost 6 points.
I check and realize that I was wrong because of a .1% error..yes a .1% error in my answer to two problems.
In one problem worth 3 points I wrote down 99.8% when the answer was 99.7 percent...lost all point for that and I was using the table in the book
Then on another problem I wrote down 777 as the answer when it was really get this...776.22
Such BS
And I was using the normal distribution tables in the book. And i set the calculator to 3 decimals of accuracy as instructed.
ON the z-value table I had to choose between .1985 or .2014 (for an integral of aprox of .20) and I went with the later which gave me the 777 answer. lame
And no I'm not going to bring it up with her because I will get the same answer I have always gotten since I was in 5th grade with regards to teachers-They are are right I am wrong..blah blah blah
Sorry for wasting your time if you read this
