Answer:
The critical value for the linear correlation coefficient is 0.765.
Step-by-step explanation:
The number of sample values is, <em>n</em> = 10.
The significance level of the test is, <em>α</em> = 0.01.
The hypothesis can be defined as follows:
<em>H₀</em>: The correlation coefficient is 0, i.e. <em>ρ</em> = 0.
<em>Hₐ</em>: The correlation coefficient is not 0, i.e. <em>ρ</em> ≠ 0.
The critical value of the test is the Pearson's Correlation coefficient critical value.
The critical value is computed using the significance level and the sample size.
So, for <em>n</em> = 10 and <em>α</em> = 0.01, the critical value is,
*Use the Pearson's Correlation coefficient critical value table.
Thus, the critical value for the linear correlation coefficient is 0.765.
