Under which situation Normal distribution will be used. The annual salaries of employees in a large company are approximately normally distributed with a mean of 50,000 and a standard deviation of 20,000. (a) What is the probability of people earns less than 40,000? (b) What is the probability of pe
Under which situation Normal distribution will be used. The annual salaries of employees in a large company are approximately normally distributed with a mean of $50,000 and a standard deviation of $20,000. (a) What is the probability of people earns less than $40,000? (b) What is the probability of people earns between $45,000 and $65,000? (c) What is the probability of people earns more than $70,000?[10]
- Distribution: Normal (approximately) - Mean $\mu = 50{,}000$ - Standard deviation $\sigma = 20{,}000$ - Required: - (a) $P(X < 40{,}000)$ - (b) $P(45{,}000 < X < 65{,}000)$ - (c) $P(X 70{,}000)$ --- The normal distribution is applied when: 1. The variable is continuous and can take any value in...
