I'm in an intro to stats class right now, and have absolutely no idea what's going on. How would I solve the following problem using R?
"Let x be a continuous random variable that has a normal distribution with a mean of 71 and a standard deviation of 15. Assuming n/N is less than or equal to 0.05, find the probability that the sample mean, x-bar, for a random sample of 24 taken from this population will be between 68.1 and 78.3"
I'm really struggling on this one and I still have to get through other problems in the same format. Any help would be greatly appreciated! If it helps, my professor has been using pnorm and qnorm a lot, I'm not sure if either of those are applicable to this problem though.
Before anyone comments berating me to just go see my professor for help, the office hours directly conflict with my work schedule, and yes, the test is in 2 days~ sorry this is one of my lower priority classes.
