The Binomial Distribution in R:

# return PMF. prob is the probability of success . x can be a list dbinom(x, size, prob)# CDF pbinom(x, size, prob)# returns a value for a particular percentile qbinom

The Normal Distribution in R:

# pdf dnorm(x, mean, sd) # cdf pnorm # percentile qnorm

要执行t-test或者查看置信区间，可以这样做：即设置数据、α的值。

> x=c(15, 18,6,20, 10, 11,9,6, 14, 14, 11,8, 10,1,7,1, 18, 17, 10, 9)> t.test(x, conf.level=0.95)One Sample t-testdata:x t = 9.0705, df = 19, p-value = https://www.songbingjia.com/android/2.473e-08 alternative hypothesis: true mean is not equal to 0 95 percent confidence interval: 8.26943 13.23057 sample estimates: mean of x 10.75

如果是做假设检验，则需要设置μ0和备选假设。
