The scores at a golf course recorded last year followed a normal distribution with mean 78 and standard deviation 11. You choose an SRS of 15 scores and calculate x = mean score. Which of the following are the mean and standard deviation of the sampling distribution of x ? a
Mean = 78, SD = 11
b
Mean = 74 , SD = 12
c
Mean = 78, SD = 11/√15
d
Mean = 75 , SD = √11
