The father of a senior high school student lists down the expenses he will incur when he sends his daughter to the university. At the university where he wants his daughter to study, he heard that the average tuition fee is at least Php20,000 per semester. Suppose from a simple random sample of 16 students, a sample mean of Php 19,750 was obtained. Further, the variable of interest, which is the tuition fee in the university, is said to be normally distributed with an assumed population standard deviation equal to Php 400. Test the hypothesis at α=0.05.

Question

The father of a senior high school student lists down the expenses he will incur when he sends his daughter to the university. At the university where he wants his daughter to study, he heard that the average tuition fee is at least Php20,000 per semester. Suppose from a simple random sample of 16 students, a sample mean of Php 19,750 was obtained. Further, the variable of interest, which is the tuition fee in the university, is said to be normally distributed with an assumed population standard deviation equal to Php 400. Test the hypothesis at α=0.05.

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.
