Finding z score with probability
WebYou should use the exact binomial approach. You can get it in Excel or any statistical program / language (R, SAS, Stata, SPSS). In Excel BINOMDIST (13,75,20%,TRUE) gives the probability of 13 or fewer songs being from Lady Gaga. One minus that will give you the other tail (remember that the binomial is discrete, therefore the cutpoint matters) WebRow labels of Table A.1 give possible z-scores up to one decimal place. The column labels give the second decimal place of the z-score. The cumulative probability for a value equals the cumulative probability for that value's z-score. Here, probability speed less than or equal 73 mph = probability z-score less than or equal 1.60.

WebAnd if I want to know what is the z-score, I'm going to say norm.s Dot inverse, remember z score is always about how many standard deviations away are you from the mean based on a standard normal distribution. So all it asks is probability, it doesn't need to know mean, it doesn't needs to know standard deviation because it's a standard normal. iit handwritten notesWebHow do we find the Z score? First, convert the variance (σ 2) to standard deviation (σ) by taking its square root: σ = √90000 = 300.
