Perform a Correction t-test. Test if p = 0 at the 10% level of significance using a two-sided test, where p is the population Pearson correlation coefficient. The test must include the following: (1) State the hypotheses to be tested. (ii) Determine the rejection region. (iii) (iv) State the decision to be made. (v) Draw a conclusion in accordance with the result obtained in part (iv). Compute the value of the test statistic.
