Given:
value of the test statistic is t20 = 1.95
corresponding p-value of 0.0653 at the 5% significance level
No, I can't conclude that the correlation coefficient differs from zero because the p-value, which is 0.0653 exceeds 0.05.
The correlation coefficient differs from zero when the p-value is less than 0.05.
If y = x then it would just be y = x. A straight line going up through the origin.
Answer:
the coefficient 2 is the slope (each coordinate is 2 units up and 1 unit right from the previous unit)
the constant 3 is the y-intercept (0, 3)
Step-by-step explanation:
A giant star is a star with substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature. They lie above the main sequence (luminosity class V in the Yerkes spectral classification) on the Hertzsprung–Russell diagram and correspond to luminosity classes II and III.
The points lie on the line, I believe, since they're part of it.
