Using the cigarette data in Exercise 6.5-7, find 95% confidence intervals for α, β, and σ2 under the usual assumptions. In Exercise 6.5-7 By the method of least squares, fit the regression plane y = β1 + β2x1 + β3x2 to the following 12 observations of (x1, x2, y): (1, 1, 6), (0, 2, 3), (3, 0, 10), (–2, 0, –4), (–1, 2, 0), (0, 0, 1), (2, 1, 8), (–1, ...Assume that the weight of cereal in a “12.6- ounce box” is N(μ, 0.22). The Food and Drug Association (FDA) allows only a small percentage of boxes to contain less than 12.6 ounces. We shall test the null hypothesis H0: ...Let X and Y denote the weights in grams of male and female common gallinules, respectively. Assume that X is N(μX, σ2x) and Y is N(μY, σ2Y). (a) Given n = 16 observations of X and m = 13 observations of Y, define a test ...Let p denote the probability that, for a particular tennis player, the first serve is good. Since p = 0.40, this player decided to take lessons in order to increase p. When the lessons are completed, the hypothesis H0: p = ...Post your question
