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.
