Setting y=0, we can solve the quadratic equation or factor the polynomial to
(5x-1)•(5x-1) = 0
(5x-1)^2 = 0
5x-1=0
x=1/5 or 0.2
So there is only one root and the function intersects the x-axis at only one point.
The answer is B. 1.

k0ka [10]

Using a calculator, it is found that for the two-tailed test of significance, the p-value is of 0.9195.

The correlation coefficient is also called <u>Pearson's r-score</u>, and is used for two-tailed tests. To find the p-value, the information needed is:

  • The value of the Pearson's r-score, that is, the value of the correlation coefficients.
  • The sample size.

In this problem, we have that the correlation coefficient is of r = 0.02, with a sample size of n = 28.

  • Using it as the input for a r-score calculator, the p-value is of 0.9195.
