Question
of rice, which is resistant to an herbicide, was crossed with another type of rice, which is susceptible to the A type herbicide. It is supposed that thoir offispring will have a 1:2:1 ratio measuring the number of plants that are resistant, moderately resistant and susceptible to the herbicide. A crop of 3120 offspring was comprised of 772 resistant, 1611 moderately resistant and 737 susceplble plants The null hypothoses for this chi-square goodness-of-fit tost is OA Ho: The distribution of the proportions is not uniform O C. Ho p-1 and Pm 2 and Ps OD. Ho: The distribution of the proportions is uniform: Pr"PmPs 0.05 points Save Answer Question 6 Refer to question number 5: The alternative hypothesis is OA. Ha: the proportions are not all the same O8. Ha The distribution of the proportions is not uniform OC. Ha: The distribution specified by Ho is not true 0.1 points Save Answer Question 7 Refer to question number 5: The expected count of rice that is susouptible to the herbicides O A. 737 OB. 780 OC. 184.25 D. 1560. 0.1 points Save Answer Question 8 Refer to question number 5: The contribution to the chi-square statistic for the rice that is susceptible is to the herbicide is about A. 0.893 B. 2.371 OC.251 D. 0.055.Explanation / Answer
