Answer:
as number of friends decreases, level of shyness increases
Explanation:
The correlation coefficient can take values which ranges from +1 to -1.
0 is a value which shows that any two variables are not associated with each other. A value that is more than 0 shows the positive association, that is, one variable's value increases as the other variable's value do so.
Here in the question the correlation coefficient of –.8 shows that the level of shyness increases as the number of friends increases.
Thus the answer is --
as number of friends decreases, level of shyness increases.
Answer:
a. When we reject null although it was true.
b. When we fail to reject null although it was false.
Explanation:
A type I error occurs when we reject a null hypothesis when it is actually true.
Thus in this case Type I error will occurs when we have a strong evidence that Buzz a dolphin could communicate. But we still reject this and conclude that it cannot communicate and we are only guessing.
Type II error occurs when we fail to reject a null hypothesis although it is false. So when we do not have a strong evidence that Buzz the dolphin can communicate and we still conclude that it can, it is said that we have incurred type II error.
