A study was conducted by the department of zoology at the Virginia tech to estimate the difference in the amount of the chemical orthophosphorus measured at two different stations on the James river. Orthophosphorus was measured in milligrams per liter. fifteen specimen were collected from station 1, and 12 specimens were obtained from station 2. the 15 specimens from station 1 had an average orthophosphorus content of 3.84 milligrams per liter and a standard deviation of 3.07 milligrams per liter, while the 12 specimens from station 2 had an average content of 1.49 milligrams per liter and a standard deviation of 0.8 milligrams per liter. Assume the observations came from normally distributed populations with different variances. A) compute the test statistic and the p-value. B) Based on the p-computed, make decisions regarding the null and the alternative hypothesis. Level of significance = 0.04

QUESTION 7 6 continued. Based on the p-value computed, make decisions regarding the null and the alternative hypotheses. Level of significance of = 0 The p-value is smaller than the level of significance. Reject the null hypothesis. Do not support the alternative hypothesis. O O The p-value is smaller than the level of significance. Reject the null hypothesis. Support the alternative hypothesis. O The p-value is not smaller than the level of significance. Do not reject the null hypothesis and do not support the alternative hypothesis. O The p-value is not smaller than the level of significance. Do not reject the null hypothesis. Support the alternative hypothesis
