Question: c) what is the probability a sample mean profit X is more than $2990.75 if n=4 and profit X is normally distributed with mean $3000

c) what is the probability a sample mean profit X is more than $2990.75 if n=4 and profit X is normally distributed with mean $3000 with standard deviation $200 this is the probability a random sample is larger than your sample (2990.75-3000)/100= -0.925
