Question

(Pls make the solution clear ty) 1. The average expenses of the Dela Cruz Family is P12,600 every half of the month with a standard deviation of P1,570. If their expenses are normally distributed, what is the probability of the family consuming less than P11,000 in one half of a month? 2A company’s profit follows a normal distribution with a mean of P500,00 a month and a standard deviation of P50,000. What will be the company’s lowest 20% possible profit?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
