The television habits of children were observed and found out that the standard deviation is 12.4 hours per week. 2. A newspaper article stated that students in the country take an average of 4 years to finish their undergraduate degrees. Suppose that you believe the mean time is longer, you conducted survey on 49 students. The result obtained a sample mean of 5 with a sample standard deviation of 1.2. 3. According to DOLE, registered nurses in government earned an average monthly salary of P9,700. For that same year, a survey was conducted on 41 registered nurses to determine if the mean salary is higher than the previous survey.

Based on the data provided in a known website article entitled "Tuition Fee Guide: 2019 Cost of College Education in the Philippines", the average tuition fee in private colleges and universities is greater than P145,000 a year. Suppose that we want to perform a hypothesis test to find whether the average tuition fee is greater than P145.000. a. Determine the null and alternative hypotheses for the hypothesis test. b. Classify the hypothesis as two-tailed, left-tailed, or right-tailed. 2. A traffic enforcer believes that the number of cars passing through a certain intersection during rush hours in weekdays follows a normal distribution with an average of 800. A new highway is opened, and it is hypothesized that the number of cars passing through the intersection will decrease as a result. A sample of 15 weekdays is taken, and the mean number of cars passing through the intersection is 750 with a sample standard deviation of 42. a. Determine the null and alternative hypotheses for the hypothesis test. b. Classify the hypothesis as two-tailed, left-tailed, or right-tailed. 18
