Consider the data set given below 1.1. Consider the data set given by x = c(0.725,0.429,-0.372 ,0.863).What value of \(\mu\) minimizes \(\Sigma((x - \mu)ˆ2)\)? x <- c(0.725,0.429,-0.372 ,0.863) x ## [1] 0.725 0.429 -0.372 0.863 mean(x) ## [1] 0.41125 x <- c(0.725,0.429,-0.372 ,0.863) mean(x) ## [1] 0.41125 p<-c(0.25, 0.25, 0.25, 0.25) x...

Common Distributions Suppose we roll a fair six-sided die 3 times. What is the probability of getting exactly 2 sixes? For our notation, let X be the number of sixes obtained in the 3 rolls. Then X has a binomial distribution with n = 3 and p = 1/6. dbinom(2, 3, 1/6) ## [1] 0.06944444 The R function dbinom computes the pmf of a binomial distri...

Suppose we roll a fair six-sided die 4 times. What is the probability of getting exactly 2 sixes? Hint: Let X be the number of sixes obtained in the 3 rolls. Then X has a binomial distribution with n = 4 and p = 1/6. dbinom(2, 4, 1/6) ## [1] 0.1157407 Suppose we were going to flip a biased coin 6 times. The probability of tossing a head is ...
