A study was conducted with alpha = 0.05 to determine if there is a significant linear correlationbetween the number of credit hours earned at the time of taking statistics101 and the grade in the course. Eight pairs of datawere collected.
The linear correlation coefficient is y = 0.6777
Pick the correct answer
a. There is a significant linear correlation
b. There is not a significant linear correlation
Determine the proportion of variation in grade that can be explained by the linear correlation between the grade and the number of credit hours earned at the time of taking the course. (round to nearest hundredth).
The correct answer is that there is a significant correlation, because the value of the correlation …
This solution identifies the correct relationship of linear correlation and determines the proportion of variation in grade with explanations.
