Answer:
D. Highest increase in the multiple R2.
Step-by-step explanation:
Included variables in a multiple regression model are those variables which have the most effect on the model ; variables which have no effect on the performance of the model ar discarded. Model performance are based on the variables affect the multiple R² value of the model. The R² value is the coefficient of determination which gives the proportion of change in predicted value based on the regression line. Higher R² value means the variable has greater effect in the model performance. Therefore, variables which have the highest increase on the multiple R² value , are included.
Answer:
0.778
Step-by-step explanation:
P(an Internet user posts photos that they have taken themselves/they post videos that they have taken themselves)=P(A/B)=?
According to conditional probability definition,
P(A/B)=P(A∩B)/P(B)
P(A)=0.54, P(B)=0.36, P(A or B)=0.62.
P(A or B)= P(A) +P(B) -P(A∩B)
P(A∩B)=P(A)+P(B)-P(A or B)
P(A∩B)=0.54+0.36-0.62
P(A∩B)=0.9-0.62
P(A∩B)=0.28.
P(A/B)=0.28/0.36
P(A/B)=0.778
So, the conditional probability that an Internet user posts photos that they have taken themselves, given that they post videos that they have taken themselves is 0.778.
