Answer to these? With Explanations

10.1 - 10.4 Quiz Practice Researchers conducted an experiment designed to reveal whether quail could choose an optimal camouflaged environment in which to lay their clutch of eggs. A random sample of quail were put into an enclosure with four different colored sand floors that were randomly placed. The researchers then ranked each clutch that was laid by how well the color of the spots matched the color of the sand floor. A rank of 1 means that the sand floor was the best match for the color of the spots and a rank of 4 means the sand floor was the worst match for the color of the spots. Do these data give convincing evidence of a difference in the proportion of clutches in each camouflage rank? Carry out an appropriate chi-square test at the o =.05 level. Camouflage rank 1 2 3 4 Observed counts 88 44 24 23Several treatments are widely used to help smokers quit smoking. One study compared ve different treatments against a placebo treatment. Subjects were randomly assigned to a treatment. The response variable was whether subjects abstained from smoking for six months after the end of the treatment. Type of treatment SUCCESS Abstinence a. Make an appropriate graph to display the results of the experiment. Briefly comment on what the graph reveals. b. Show how you would compute the expected value for the subjects who used the \"Patch\" treatment who ultimately abstained from smoking. What value does this category contribute the chi-square statistic? Show how you calculated this. c. Is there evidence at the o: = .05 level that there is an association between the type of treatment and whether or not subjects abstained from smoking? Feel free to use the calculator matrix for this. (Do this part on a separate sheet of paper) :1. What treatment showed the most signicant difference from what was expected (under the assumption that all treatments produce proportional outcomes)? Look at the \"CompMan'ix\" to answer this, if you used matrices
