Question
sity of unrequited love among three groups-individuals who were currently experiencing unrequited love, those who had previounly were to experienoe it. The results of the study are summarized in the accompanying table. Determine the significance of the dfterence among experienced unrequited love and described their they would feel if they groups, using the 5% level. Completo parts (a) through (d) below.

(a) Use the steps of hypothesis tosting. First determine the null and research hypotheses. Choose the correct answer below. O A. The null hypothesis is that the population means are not the same. The research hypothesis is that at least two of these populations have the same mean O B The rull hypothesis is that these populations have the same mean (m-u2·m) The researon hypothesis is that te population means are not the same C. The rul' hypothesis is that the population means are not the same The research hypothesi.. that these populato s have the same mean p -a,-Pa O D. The Determine the characteristics of the comparison distribution. The comparison distributon will te an Fdistribution with enand dan Determine the cutoff sample score on the comparison distribution at which the null hypothess should be rejected. Al the 0.06 level, the cutoff F is (Round to two decimal places as needed.) Determine the sample's score on the comparison distribution Fe? (Round to two decimal places as needed.) ati null hypothesis is that at least two of these populations have the same mean. The research hypothesis is that the population means are not the sameExplanation / Answer
Sol:
H0:all the 3 group means are equal
H1:atleast one the means are different
SolutionA:
OPTION B
