4. Linear regression question: An experiment carried out to investigate the design of two variables x and y as follows: X: 303 313 323 323 333 340 343 353 353 364 Y: .96 .83 .72 .73 .65 .60 .58 .52 .53 .46

a)Draw a scatter plot and list your observations.

b) Plot ln(y) against 1/x. What does this plot suggest?

c) Fit a straight line to the transformed data of part b and use that line to predict the value of y when x is 325. (10)

An experiment was carried out to investigate the effect of species (factor A, with I = 4) and grade (factor B, with J = 3) on breaking strength of wood specimens. One observation was made for each species—grade combination—resulting in SSA = 443.0, SSB = 424.6, and SSE = 125.4. Assume that an additive model is appropriate. (a) Test H0: α1 = α2 = α3 = α4 = 0 (no differences in true average strength due to species) versus Ha:...

Question 2: An investigation has been carried out to investigate which of the beverages that two separate companies put on the market is consumed more by consumers. In the first sample of 100 people, the average monthly consumption was 5 liters, in the second sample of 110 people, the average monthly consumption was 7 liters, and the standard deviations were 2 and 3 liters, respectively. Test unilaterally according to the 5% significance level.

Question 1 A pharmaceutical company carried out a study to investigate if men and women, of the same age, have different levels of the high density lipoprotein (HDL) type of cholesterol. This is the type of cholesterol that is labelled “good” as it helps prevent coronary disease. A small volunteer sample of men and women aged 40-45 of general good health was taken as a preliminary trial. Their blood HDL cholesterol levels (mg/dL) were measured with the following results: MALE:...

(Linear combinations). For the purpose of this question, the random variables X and Y are independent normal X ∼ N(12, 3) and Y ∼ N(15, 4), where the two arguments are the mean and standard deviation, so the variances are 9 and 16 respectively. If a, b are two constants, the linear combination aX +bY is normally distributed with mean 12a + 15b and variance 9a 2 + 16b 2 . Hence or otherwise, compute the following probabilities: Part a:...
