Solve for what is asked is each problem below. 1. There is a claim that on daily average, students spend 5.5 hours on social media with a standard deviation of 1.25. A researcher wants to test the claim at 5% level of significance. 1. Formulate the null and alternative hypothesis 2. Determine the test statistic to be used 3. Find the corresponding z- value 4. Identify the rejection regionPART 2. TEST FOR DIFFERENCE BETWEEN TWO MEANS. Answer the following problems. Use the 6 steps in hypothesis testing enumerated in the What's New section of your module. 3. The weights of babies who were given two types of diets were recorded as follows. Diet A Diet B X1 = 5.80 2 = 5.73 $1 = 1.04 $2 = 1.13 nj = 14 n2 = 14 At 0.05 level of significance, test whether the average weights of babies under diet A is significantly higher than those under diet B
