Salaries of a city follows a normal distribution with average salary of $1 million. Assume that salary is normally distributed. Suppose a sample of 60 citizens was taken. The sample standard deviation is $0.1 million. (a) What is the standard error for the sample mean salary? (b) What is the probability that the sample mean salary is more than $1.2 million? (c) What is the probability that the sample mean salary is less than $1.4 million? (d) What is the probability that the sample mean salary is between than $1.1 million and $1.3 million?
