Hi everyone,

I'm starting to learn matlab.

I would love if anyone could help me write this code in matlab:)

speed = [28 -44 29 26 27 22 23 33 16 24 40 21 31 34 -2 25 19];

newSpeed= speed-mean(speed)+33.02;

> bstrap <- c()

> for (i in 1:1000){

+ newsample <- randsample(newspeed, 20, replace=T)

+ bstrap <- c(bstrap, mean(newsample))}

> hist(bstrap)

p= (sum(bstrap < 21.75) + sum(bstrap > 44.29))/1000

I think MATLAB has a built-in function that you can use instead of the R for loop. Try just:

newSpeed= speed-mean(speed)+33.02;
bstrap = bootstrp(1000,@mean,newspeed)
histogram(bstrap);
