1- Suppose that a sample of 35 pairs of data produced a test statistic of r = 0.335. A significance level of αα = 0.10 is to be used. (a) Find the critical values that would be used to test for significant linear correlation. Do not type "±±" in front of your answer (the ±± is already given in front of the answer box below). Round your answer to 3 places after the decimal point, if necessary. r = ±±...

(a) Suppose n = 6 and the sample correlation coefficient is r=0.894. IS significant at the 1% level of significance (based on a two-tailed test)? (Round your answers to three decimal places.) critical Conclusion: Yes, the correlation coefficient p is significantly different from 0 at the 0.01 level of significance. No, the correlation coefficient p is not significantly different from 0 at the 0.01 level of significance. (b) Suppose n = 10 and the sample correlation coefficient is r =...
