For MEMBER 5: The number of demons slayed by the demon slayers per three yearsis known to be normally distributed with an average of 2560 and a standard deviationof 1419.The mean and standard deviation of the sample mean is given byMean= µz = µ= 2560Standard deviation(og) = 0/Vn= 1419/v5=634.60Standard deviation(oz) = 634.60 3. Let's assume that your sample mean and sample standard deviation are the truepopulation mean and standard deviation,,compute for the following probabilities:a. P[X < 2750]Z-score: 6.28P[Za]= 0

Let μ be the population mean and σ be the standard deviation. Let X be a random variable. Then,…
