A Random Sample of Two Variables, X and Y, Produced

Question 113

Multiple Choice

A random sample of two variables, x and y, produced the following observations: A random sample of two variables, x and y, produced the following observations:   Test to determine whether the population correlation coefficient is negative. Use a significance level of 0.05 for the hypothesis test. A)  Because t = -4.152 < -1.9432, reject the null hypothesis. Because the null hypothesis is rejected, the sample data does support the hypothesis that there is a negative linear relationship between x and y. B)  Because t = -4.152 < -1.9432, do not reject the null hypothesis. Because the null hypothesis is not rejected, the sample data support the hypothesis that there is a negative linear relationship between x and y. C)  Because t = -9.895 < -1.9432, reject the null hypothesis. Because the null hypothesis is rejected, the sample data does support the hypothesis that there is a negative linear relationship between x and y. D)  Because t = -9.895 < -1.9432, do not reject the null hypothesis. Because the null hypothesis is not rejected, the sample data support the hypothesis that there is a negative linear relationship between x and y. Test to determine whether the population correlation coefficient is negative. Use a significance level of 0.05 for the hypothesis test.
