Answer Happy

For question 1 I put C
C F M N O 5 U Number of interactions 28 40 A study tried to identify activities that help managers' success. To measure manager's success an index was devised where higher score indicates larger success in the company. One element of interest to the researchers was the 'amount of interactions with outsiders in relation to the manager's success. Data were collected for 19 managers that included the index of success and the number of interactions with outsiders.

The prediction equation that predicts the success score is: : a. Success Score= 24.81+6.68*Interactions b. Success Score=0.60 + 24.81*Interactions c. Interactions = -3.01 +0.92*Succerss Score d. None of the above 2. John StatDud selected answer 'b'as the correct answer of question 1 above. He interperted the model's coefficients using the equation Success Score=0.60 + 24.81*Interactions. Whether correct or not, based on this equation answer questions 2.1 and 2.2 2.1 Which answer would be correct for John from the answers provided below? a. For every unit of the slope, the intercept increases by 24.81 units. b. One unit increase of the slope leads to 0.60 units increase of the success score C. The slope means that for every unit increase of the success score, the number of interactions will increase by 24.81 on the average. d.
