Answer:
Coefficient of determination = 0.149769
Step-by-step explanation:
We are given the following in the question:
Coefficient of correlation, r = -0.387
We have to find the coefficient of determination.
Coefficient of determination =
Coefficient of determination:
- It tells us about the variation explained in the model.
- This correlation of determination tells that 14.98% of the variation is explained in the model that is we can say that the independent variable explains 14.98% changes or prediction in the dependent variable.
- It ranges from 0 to 1 and a correlation of determination of 1 means that the dependent variable is 100% predicted by the independent variable.
- Correlation of determination of 0 means that the dependent variable cannot be predicted by the independent variable.

Answer:
1. The probability that the student will get exactly 6 correct answers is .
2. The probability that the student will get more than 6 correct answers is .
Step-by-step explanation:
From the given information it is clear that
The total number of equations (n) = 10
The probability of selecting the correct answer (p)=
The probability of selecting the incorrect answer (q)=
According to the binomial distribution, the probability of selecting r items from n items is
where, p is probability of success and q is the probability of failure.
The probability that the student will get exactly 6 correct answers is
Therefore the probability that the student will get exactly 6 correct answers is .
The probability that the student will get more than 6 correct answers is
Therefore the probability that the student will get more than 6 correct answers is .
