Ten pairs of points yielded a correlation coefficient r of 0.790. If a=0.05, which of the following statements is correct if H: p= 0? Because 3.644 is greater than -2.306, the null hypothesis is not rejected. Because 3.644 is greater than 2.306, the null hypothesis is rejected. Because 3.644 is greater than 1.860, the null hypothesis is rejected. There is no correlation between the variables. Save Aniswe It is believed that children can throw a ball further after lunch than before lunch. A researcher decided to investigate this hypothesis using the paired-sample sign test. Each of 14 children threw a ball as far as they could before and after lunch. The distances in meters are tabulated below.

The data does not support the claim (does not reject the null hypothesis) because the test value 3 is equal to the critical value 3. The data does not support the claim (does not reject the null hypothesis) because the test value 4 is less than the critical value 7. The data supports the claim (rejects null hypothesis) because the test value 3 is more than the critical value 2
