In an experiment with t = 4 population means and sample sizes of n₁ = 5, n2 = 6, n3 = 4, and n4 = 8, consider the four linear combinations of the sample means: 1₁ = ₁ + 3y2 + 3 + y4 1₂ = ₁ + y₂ - 274 13= ₁ + 2 + 3 +Y4 Î4 = V₁ + y2 - 3y3 + y4 a. Which of the four linear combinations are contrasts b. Which pairs of contrasts are orthogonal

A bank is opening a new branch in one of neighborhoods. One of factors considered by the bank was whether the average monthly family income (in thousand pesos) in the two neighborhoods differed. From census records, the bank drew two random samples of 100 families each and obtained the following information: Sample A: x = 10,800; ơ = 300; n = 100 %3D %3D Sample B: x2 = 10,300; 02 = 400; n2 = 100 %3D %3D %3D The bank claims that the two neighborhoods have the same mean income. Is the bank correct? Test the hypothesis using a = 0.10.
Do larger universities tend to have more property crime? University crime statistics are affected by a variety of factors. The surrounding community, accessibility given to outside visitors, and many other factors influence crime rate. Let x be a variable that represents student enrollment (in thousands) on a university campus, and let y be a variable that represents the number of burglaries in a year on the university campus. A random sample of n = 8 universities in California gave the following information about enrollments and annual burglary incidents. x 12.9 29.0 24.5 14.3 7.5 27.7 16.2 20.1 y 28 72 39 23 15 30 15 25 (a) Make a scatter diagram of the data.
