The median pH level of the rain in a certain county, was 4.90. A biologist obtains a random sample of 19 rain dates and obtains the following data. Test the hypothesis that the median pH level has decreased from 4.90 at the a= 0.05 level of significance. Test the given hypothesis. O A. Reject Ho because the test statistic is greater than the critical value. O B. Do not reject H, because the test statistic is greater than the critical value. O C. Do not reject H, because the test statistic is less than or equal to the critical value. O D. Reject H, because the test statistic is less than or equal to the critical value.
