What are the characteristics of standard normal distribution

What are the characteristics of standard normal distribution? The HR department of an organization collects data on employees\' age, salary, level of education, gender, and ethnicity. Which data do you think is more likely to follow normal distribution? Explain why.

Solution

Standard normal distribution is symmetrical about mean and bell shaped. The mean and standard devitaion for a standard normal distribution is 0 and 1 respectively. Employee\'s age should follow normal distribution because no employee would be very young or very old. The salary should be right skewed because there wiuld be some employees whose salaries must be very large than others.
