Document Summary
A company claims that each batch of its deluxe mixed nuts contains 52% cashews, 27% almonds, 13% macadamia nuts, and 8% brazil nuts. Calculate the chi-square statistic for the data in exercise 1. Show your work: roulette calculate the chi-square statistic for the data in exercise 2. Refer to exercise 1 and exercise 3. (a) confirm that the expected counts are large enough to use a chi-square distribution to calculate the p-value. What degrees of freedom should you use? (b) sketch a graph like figure 11. 4 (page 685) that shows the p-value. (c) use table c to find the p-value. Justify your answer: birds in the trees researchers studied the behavior of birds that were searching for seeds and insects in an oregon forest. In this forest, 54% of the trees were douglas firs, 40% were ponderosa pines, and 6% were other types of trees.
