Question 17 (2 points) Five independent random samples, nj =5, n2 = 4, ng= 6, n5= 6, and n4 = 6 were analyzed using ANOVA. What was the degrees of freedom for error in the ANOVA table? Your Answer: Answer Question 18 (2 points) The useful life of an electrical component has a standard deviation of 38.0 hours. If a sample of 35 light bulbs of this type is to be taken, find to two places of decimal the probability that the sample mean useful life, X, will be less than 10.0 hours from the true value, H. Your Answer: Answer Question 19 (2 points) If you were to perform one-way completely randomized analysis of variance, ANOVA, to test the hypothesis that the following three samples come from populations having the same mean, what would be the value of the Total Sum of Squares (to the nearest whole number)? Ex Ex Sample 1: 14 15 21 19 28 17 21 158 3266 Sample 2: 26 21 34 28 33 142 4146 Sample 3 15 20 23 24 Don't do the entire test, you are only asked to find SST Source d.f. Sum of Squares Mean Square F TotalUsing the regression methods studied in STAT 263, find the expected value of y, y, when x=9. State your answer to one place of decimal.

Your Answer: Answer Question 22 (2 points) Consider the following frequency table of 100 observations on the random variable X. Value of x 1 2 3 Observed frequency 16 31 23 20 10 If you were to do a Goodness of Fit test on this data to see if the Poisson distribution was a good fit to the data, state your expected frequency (to one place of decimal) for x = 1. Do not do the entire test. You are asked for only one expected value. Your Answer: Answer Question 23 (2 points) How = 122.50 Hip > 122.50 7 = 43 ( = 14.60 Q = 0.05 Find (to two places of decimal) the value of the sample mean at which your decision would change from reserving judgment to rejecting the null hypothesis Your Answer: Answer Question 24 (2 points) In an experiment on colour inheritance in a particular flower, of 1115 self-fertilized plants, 260 plants had blue flowers, 290 plants had yellow, and 565 had red. Theory predicts the flowers should be 25% blue, 25% yellow, and 50% red. Do the observed data support the theory? If you were to do a goodness of fit test on this data to test the hypothesis that the theory is correct, state to one place of decimal the expected frequency for the yellow cell
