Let the random variable X follow normal distribution with mean 88.4 and standard deviation 94.5
Here sample size n=79
We need to find the probability that
[ round to four decimal place]
The probability is 0.5714
The distribution of sample mean is given by,
So, here
We need to find
The probability is 0.9451
