- A sample of n=10,000 (x, y) pairs resulted in r= .022. Test H0: p=0 versus Ha: p=? 0 at significance level .05. Is the result statistically significant? Comment on the practical significance of your analysis.For a given confidence interval and significance level, and assuming a relatively small sample size, say 25, the relationship between a T critical value and a Z critical value can be best expressed as: T-Value > Z-ValueAt the a=.05 level of significance, can we reject the null hypothesis in part (a)? Calculate the value of the test statistic (to 2 decimals). The p-value is
