The C. F. Eye Care company manufactures lenses for transplantation into the eye following cataract surgery. An engineering group has conducted an experiment involving two factors to determine their effect on the lens polishing process. The results of this experiment are summarized in the following analysis of variance display:| Source | SS | DF | MS | F ||-------------|-----------|----|---------|-------|| Factor A | ? | ? | 0.0833 | 0.05 || Factor B | 96.333 | ? | 96.3333 | 57.80 || Interaction | 12.167 | 2 | 6.0833 | 3.65 || Error | 10.00 | 6 | ? | ? || Total | 118.667 | 11 | | |Answer the following questions about this experiment:a. The sum of squares for factor A is: _______ b. The number of degrees of freedom for factor A in the experiment is: _______ c. The engineers used _______ levels of the factor A in this experiment. d. The engineers used _______ levels of the factor B in this experiment. e. There are _______ replicates of this experiment.

The Airline Passenger Association studied the relationship between the number of passengers on a particular flight and the cost of the flight. It seems logical that more passengers on the flight will result in more weight and more luaggage, which in turn will result in higher fuel costs. For a sample of 13 flights, the correlation between the number of passengers and total fuel cost was .37. Is it reasonable to conclude that there is positive association in the population between the two variables? H0: p≤0 Ha: p >0 Use the 5% significant level, what is the p-value?____________ What is your decision regarding H0 or the hull hypothesis? Reject or Do not Reject______________ Draw a conclusion. Specifically, what does this indicate about the question?
"A large candy manufacturer produces, packages and sells packs of candy targeted to weigh 52 grams. A quality control manager working for the company was concerned that the variation in the actual weights of the targeted 52-gram packs was larger than acceptable. That is, he was concerned that some packs weighed significantly less than 52-grams and some weighed significantly more than 52 grams. In an attempt to estimate the variance of the weights of all of the 52-gram packs the manufacturer makes, he took a random sample of n = 20 packs off of the factory line. The random sample yielded a sample variance of 3.5 grams. Use 90% confidence level. What is the confidence interval for the variance of the weight of the candy?"
