Descriptive Statistics

Question

N: 50 Min:1.00 Max:5.00 Mean: 3.9280 Std Deviation: .77065

Answer 1

so we can do this 2 ways:

Calculator: normalcdf(-99,4.7,3.928,.77065/sqrt(50))=1=100%

By hand: (4.7-3.928)/(.77065/sqrt(50)=7.083 then look this number up on a z chart which you cannot see, but since it is so far off it would be 100%
