Suppose 90 geology students measure the mass of an ore sample. Due to human error and limitations in the reliability of the balance, not all the readings are equal. The results are found to closely approximate a normal curve, with mean 86 g and standard deviation 1 g. Use the symmetry of the normal curve and the empirical rule as needed to estimate the number of students reporting readings between 85 g and 87 g. The number of students reporting readings between 85 g and 87 g is (Round to the nearest whole number as needed.) Enter your answer in the answer box.

Professor Ramos has a packing plant in a machine packs carton with jars. A sales person claims that the machine she is selling will pack faster to test the claim the times It takes each machine to pack 10 cartons are recorded in seconds and the results are shown below population one new machine n=10 Mean =42.3 s=0.685 Present machine n=10 mean=43.23 S =0.750.Do the data provide significant evidence to conclude that on the average the new machine packs faster perform the required hypothesis test in the 5% level of significance assume the population standard deviation's are equal but unknown show all your steps setting up your null and alternative hypothesis.
Suppose 140 geology students measure the mass of an ore sample. Due to human error and limitations in the reliability of the balance, not all the readings are equal. The results are found to closely approximate a normal curve, with mean 85 g and standard deviation 2 g. Use the symmetry of the normal curve and the empirical rule as needed to estimate the number of students reporting readings between 81 g and 89 g. The number of students reporting readings between 81 g and 89 g is (Round to the nearest whole number as needed.)
