1. Show the output of the following code segment.

int count=0;

                        for (int i=2; i <= 4; i++ ) {

                                    StdOut.println(i);

                                    for (int j=1; j <3; j++) {

                                                count++;

                                                StdOut.println(i +" " + j +" "+ count);

                                    }

                        }

2. Show the output of the function call statements shown.

For the fish mortality data set, use an appropriate ANOVA design to determine whether age affects proportional mortality while accounting for variation in mortality due to life history strategy. If age has a significant influence on sunfish mortality, see if you can determine which age results in a different mortality rate.

MORTALITY OF A SUNFISH AFFECTED BY LIFE HISTORY STRATEGY AND AGE

% MORTALITY: 38, 42, 14, 41, 41, 16, 36, 39, 18, 32, 36, 15, 28, 33, 17

LIFE HISTORY STRATEGY: 1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 5

AGE: 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3

I am able to do this in R, but am unsure how to do it by hand with formulas.

Data Set:

Express your answer as an integer, or as a fraction in lowest terms if necessary.

1. If g(x) = - 3 f(x),   where f(6) = 10 and f'(6) = - 4,   find g'(6).

2. If g(x) = 5 x + 6 f(x), where f(- 5) = 3 and f'(- 5) = - 10, find g'(- 5).

3. If f(x) = (e^x) / x , find f'(1).

4. Does distance from object affect the eye focus time? An industrial engineer is conducting an experiment on eye focus time. She is interested in the effect of the distance of the object from the eye on the focus time. Four distances (4’, 6’, 8’, 10’) will be studied. She has 5 subjects available for the experiment, and has decided that she will test each subject at each of the 4 distances; the order in which the distances are tested will be randomly decided for each study participant. The focus time measurements are given in the table below and are posted on in a text file Eyedata.

(a) What type of experimental design was used in this experiment?

(b) What statistical model would you use to analyze these data?

(c) What assumptions would be required for the model in (b)?

(d) What evidence do these data provide for / against the hypothesis that the distance has no effect on focus time?

(e) What contrast would you use to test for a difference between the mean focus times for distances of 4’ and 6’? Find a 95% confidence bound for this contrast and interpret.

(f) Test if there is a significant difference between the 4’ and 6’ group with the 8’and 10’ group. Clearly state the contrast you will use, find its unbiased estimator and standard error of the estimator. Next perform the test.
