A certain genetic characteristic of a particular plant can appear in one of three forms (phenotypes). A researcher has developed a theory, according to which the hypothesized proportions are p1 = 0.25, p2 = 0.50, and p3 = 0.25. A random sample of 200 plants yields X2 = 5.08. (a) Carry out a test of the null hypothesis that the theory is correct, using level of significance α = 0.05. What is the critical value for the test? (Round your...

A certain genetic characteristic of a particular plant can appear in one of three forms (phenotypes). A researcher has developed a theory, according to which the hypothesized proportions are p1 = .25, p2 = .50, and p3 = .25. A random sample of 200 plants yields χ2 = 4.68. (a) Carry out a test of the null hypothesis that the theory is correct, using level of significance α = .05. (Round your answer to three decimal places.) P-value =
Birds use color to select and avoid certain types of food. The authors of a particular article studied the pecking behavior of 1-day-old bobwhites. In an area painted white, they inserted four pins with different colored heads. The color of the pin chosen on the bird's first peck was noted for each of 33 bobwhites, resulting in the accompanying table. Color First Peck Frequency Blue 15 Green 8 Yellow 7 Red 3 Do these data provide evidence of a color...
Select the BEST answer for each of the questions below (I true, F- false). Cirele the letter that corresponds with the answer you have selected. Each question is worth 2 points. [Total 40 points) Answer uestion E1. Power is the ability to reject the null hypothesis when it should be rejected 2. With curvilinear data, the Pearson r statistic is an appropriate, accurate statistical tool In a research report, the term statistically significant is used to indicate that the null...
Chicken diet and weight. In previous chapter, we compared the effects of two types of feed at a time. A better analysis would first consider all feed types at once: casein, horsebean, linseed, meat meal, soybean, and sunflower. The ANOVA output below can be used to test for differences between the average weights of chicks on different diets.
