Please answer the questions below :

A doctor wants to study the factors that influence the systolic blood pressure. From the literature, he finds that the systolic blood pressure can be explained by gestation period, weight (kg), and age (days) for infants.

a)Develop the research model and identify the independent, dependent, mediation, and moderation variables, if any.

b)Write the hypotheses.

c)Based on the following regression output,

i.Are all basic assumptions of regression met? Explain.

ii.Is the requirement of model fit fulfilled? Explain.

iii.Interpret the output of hypothesis testing.
