Reаd the lаb descriptiоn аnd answer questiоns 1-7 Jack was tasked with determining which brand оf pen is most likely to attract a termite. He selected 5 brands of black ink pen, Bic, Precision V5, Sharpie, Papermate, Pilot, plus a pencil. Jack knows from previous experience that the termites are attracted to ink from a black Bic pen and are not attracted to lead from a pencil. To complete the experiment Jack drew a 7 cm diameter circle with each pen and placed a termite 0.25 cm from each circle. He then gave the termite 60 seconds to find the circle and travel around the circle. Jack defined positive results as a termite finding the circle within 60 seconds and then following the circle at least half way around. A negative result would be a termite that was unable to find the circle within 60 seconds or a termite that found the circle but followed it for less than half the circle. Jack tested ten termites on each brand of pen for a total of sixty termites. The results of Jack’s experiment are found in the table below. Table 1: Number of termites that found the black 7 cm diameter circle within 60 seconds and then followed the circle for at least half the total distance.

Pleаse nоte thаt this questiоn cоnsists of five pаrts. You need to any mathematical calculations/explanations to get the final answer. Just giving the answer without showing work may result in zero for the question. Researchers compare five weight loss groups - four popular weight loss programs and control group. Each of the thirty participants is randomly assigned to one of the treatment groups, six participants to each treatment group. Participants follow the assigned program for 10 weeks. The outcome of interest is weight loss (in lbs) (weight before - weight after 10 weeks). Researchers used a one-way ANOVA model to test whether or not the mean weight loss is same among the 5 groups. The incomplete ANOVA table is given below. Write down the null and alternative hypotheses for testing whether or not the mean weight loss is same among the 5 groups. Clearly define any parameters you might use. Compute the degrees of freedom missing in the ANOVA output (i.e. DF corresponding to group) Compute the Error Mean Square missing in the ANOVA output. At 5% significant level, is there sufficient evidence to claim that the mean weight loss is different for at least one of the groups. Explain your answer. The output for Tukey pairwise comparisons is given below. (i) Based on the grouping information output, is the mean weight loss for programs 1 and 2 are significantly different? Explain your answer. (ii) Based on Tukey simultaneous CIs, for which programs (from programs 1, 2, 3, 4) the mean weight loss is significantly different from the control group? Explain your answer.
