### Hypothesis Testing for Rank CorrelationA hypothesis test that the rank correlation in the population is zero is conducted at the 5% level of significance. If the rank correlation coefficient is 0.50 for a sample of 15 observations, what is the computed value of the t-statistic?#### Multiple Choice Options:- ( ) 4.088- ( ) 2.082- ( ) 0.456- ( ) 2.236To solve this problem, you can use the formula for the t-statistic in a hypothesis test for rank correlation, which is given by:\[ t = \frac{r \sqrt{n-2}}{\sqrt{1-r^2}} \]Where:- $ r $ is the rank correlation coefficient- $ n $ is the sample sizeSubstitute the given values ($ r = 0.50 $, $ n = 15 $) into the formula to find the computed value of the t-statistic.
