answer no. 2 Directions: Follow the steps in testing hypothesis to answer the following problems.a. Identify the given in the problem.b. State the null and alternative hypotheses.c. Determine the test statistic, then compute its value.d. Find the critical value and draw the critical region.e. Draw a conclusion1. The Coronavirus Disease (COVID-19) is an infectious disease caused by a new strain ofcoronavirus. The World Health Organization (WHO) claims that the incubation period of thevirus in the infected person has a mean of 5.1 days. The doctors in the Philippines conductedresearch and they found out that incubation period of the virus in human body is 6.03 days witha standard deviation of 3.32. The samples were 46 COVID patients. Is there enough evidenceto conclude that the incubation period of the virus is 5.1 days as stated, at a = 0.01?2. It is known from the records of the city schools that the standard deviation of Math test scoreson XYZ test is 15. A sample of 200 pupils from the system was taken and it was found out thatthe sample mean score is 75. Previous tests showed that the population mean to be 70. Is itsafe to conclude that the sample is significantly different from the population? Use 95%confidence level.3. Powder milk is packed in 1-kilogram. An inspector from the Department of Trade and Industry(DTI) suspects the bags may not contain 1 kilogram. A sample of 40 bags produced a mean of0.96 kilogram and a standard deviation of 0.12 kilogram. Is there enough evidence that thebags do not contain 1 kilogram? Use a = 0.01.4. A researcher knows that the average height of Filipino women is 1.53 m. A random sample of26 women was taken and found to have a mean height if 1.56 m with a standard deviation of0.1 m. Is there a reason to believe that the 26 women in the sample are significantly taller thanthe others?
