1) DOLE reports that the mean amount of earnings for full-time workers ages 25 to 34 with a master’s degree is less
than ₱70,000. In a random sample of 15 full-time workers ages 25 to 34 with a master’s degree, the mean amount
of earnings is ₱66,231 and the standard deviation is ₱,5945. At α = 0.05, is there enough evidence to support the
agency’s claim? Assume the population is normally distributed.

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.
