I measured the height of a sample of marigolds by the Union. The values were 7, 10, 12, 9, 10, 12, 10, 9, 10, 11, 8, 12, 10, 9, 11, 10, 9, 10, and 11 inches. I then walked downtown and saw some marigolds growing on Broadway, so I measured a sample of them. The values were 6, 9, 13, 10, 12, 10, 8, 11, 7, 14, 10, 12, 8, 7, 14, 9, 8, 13. Calculate the mean, the variance,...

The following values of a response Y were obtained for three settings of a categorical predictor A. A = 1 0.090 0.800 33.070 −1.890 A = 2 5.120 1.580 1.760 1.740 A = 3 5.080 −3.510 4.420 1.190 Suppose we assume the normal regression model for these data with one categorical predictor. a) If you have been able to fix any problems encountered with the model, carry out a one-way ANOVA to test for any differences among the conditional means...

Suppose that height Y and arm span X for U.S. women, both measured in cm, are normally distributed with means E(Yi) = 168, E(Xi) = 165, variances var(Yi) = 21, var(Xi) = 28, and covariance cov(Xi, Yi) = 20 for measurements on the same individual. For the purpose of this question, the variables are jointly normally distributed, and the values are independent for distinct individuals. Part a: The correlation between height and arm span is _______ Part b: The ‘albatross...

For two goods x and y, the individual’s preferences are measured by the utility function ?(?,?)= ?0.5?0.5, the price of good y is $10, income equals $100, and the price of good x increase from $5 to $10. Draw the price consumption curve for x and y and compute the slop of the price consumption curve. Show your calculation step by step.

(7) The following values were obtained for the nitrate concentration (mg/L) in a sample of river water: 0.403, 0.410, 0.401, and 0.380. The last measurement is suspect. Based on this data set only, should it be rejected? Justify your answer. (8) Three further measurements were added to those given in question (7) so that the complete results became: 0.403, 0.410, 0.401, 0.380, 0.400, 0.413, and 0.411. Should “0.380” still be retained/rejected? Justify your answer. (9) Based on questions (7) and...
