Problem One: The college bookstore tells prospective students that the average cost of its textbooks is AED 254. A group of smart statistics students thinks that the average cost is higher. In order to test the bookstore's claim against their alternative, the students selected a random sample of size 109. The mean from their random sample is AED 261 with a standard deviation of AED 45.2. Perform a hypothesis test at the 5% level of significance and state your decision. Problem Two: A certain chemical pollutant in the Genesee River has been constant for several years with mean μ = 34 ppm (parts per million). A group of factory representatives whose companies discharge liquids into the river is now claiming that they have lowered the average with improved filtration devices. A group of environmentalists will test to see if this is true at the 5% level of significance. Assume that their sample of size 50 gives a mean of 32.5 ppm and standard deviation s = 8 ppm. Perform a hypothesis test at the 5% level of significance and state your decision. Problem Three: A manufacturing process produces ball bearings with diameters that have a normal distribution. Ball bearings with diameters that are too small or too large are undesirable. In order to test the claim that μ = 0.50 centimeters, perform a two-tailed hypothesis test at the 5% level of significance. A random sample of 55 gave a mean diameter of 0.51 centimeters with a standard deviation of 0.04 centimeters. Perform a hypothesis test and state your decision. Problem Four: A group of biologists believe that the average weight of adult cinnamon bears is 325 kg. They take a sample of 12 adult bears and obtain a mean of 321 kg with a standard deviation of 2 kg. Test their belief to determine if it is true or not at a confidence level of 95%.

20 P) A 1 L buffer solution contains 30 mmol NaHSO3 and 90 mmol Na2SO3. Let's assume that we run out of materials to prepare this bumper. We have Na2CO3(k), Na2HPO4(k), 1M dimethylamine, NaOH(k) and 1M HNO3. Prepare a buffer solution with the same pH as the NaHSO3-Na2SO3 buffer using the ones you need from these materials.
