Quizplus · Accepted Answer

The chemist is using a t test to determine if the linear term is significant, which means she is testing the coefficient of the linear term. If the p-value of the t test is less than the level of significance (0.05), she would reject the null hypothesis and conclude that the linear term is significant. However, the output provided in the scenario does not include the p-value of the t test, so we cannot determine whether the chemist would make this decision or not. Therefore, the answer to this question is "True" because it is possible for the chemist to decide that the linear term is significant using a t test with a level of significance of 0.05.
