Document Summary

Continuous (not discrete ) variables have an infinite continuum of possible values: true, false . = 10*9*8*7*6*5*4*3*2*1 in r, do the following code for 10! factorial (10) Binomial test is one of the statistical techniques we can apply for data analysis: f. significance level criterion is predetermined; it is not determined by the p-value. Multiple choice answers: a, there are three trials, the first is a head, and the second is a head, and the third is a head. In each trial, the probability for getting a head is . * * = 0. 125: b, dbinom(3,4,0. 5) #[1] 0. 25, b, sum(dbinom(3:4,4,0. 5)) #[1] 0. 3125, d, sum(dbinom(0:3,4,0. 5)) #[1] 0. 9375 5. a 0. 8^3 #[1] 0. 512. Short answer: yes, the trainees showed significant changes. Alternative hypothesis: there are significant changes due to training. p value indicates whether the null hypothesis should be rejected or not.
