A researcher obtains a Pearson correlation of r = -0.30 for a sample of n = 52 participants. For a two tailed test, which of the following accurately describes the significance of the correlation? a) The correlation is significant with either alpha = .05 or alpha = .01. b) The correlation is not significant with either alpha = .05 or alpha = .01. c) The correlation is significant with alpha = .05 but not with alpha = .01. d) There is not enough information to evaluate the significance of the correlation.

A correlation analysis on 100 pairs of variables produced a Pearson's correlation coefficient of 0.29. Which of the following statements best describes this result? (Need to test significance) A. We would accept the null hypothesis. B. There is no significant correlation between the variables. C. The variables are significantly correlated but the correlation is weak. D. The correlation coefficient is not significantly different to zero at the 95% confidence level.

Conduct each test at the $\alpha=0.05$ level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, (c) the critical value, and (d) the P-value. Assume the samples were obtained independently using simple random sampling. Test whether $p_{1}>p_{2}$. Sample data: $x_{1}=368, n_{1}=541, x_{2}=351, n_{2}=593$
