You are thinking of employing a t procedure to test hypotheses about the mean of a population using a significance level of 0.05. You suspect the distribution of the population is not Normal and may be moderately skewed. Which of the following statements is correct?A) You may use the t procedure, but you should probably claim the significance level is only 0.10.B) You may use the t procedure, provided your sample size is large, say, at least 30.C) You should not use the t procedure because the population does not have a Normal distribution. D) You may not use the t procedure because t procedures are robust to non-Normality for confidence intervals but not for tests of hypotheses.

The change in water level of a lake is modeled by a polynomial function, w(x). described how to find the x-intercepts of w(x) and how to construct a rough graph of w(x) so that the parks department can predict when there will be no chage in the water level. you may create a sample polynomial of degree 3 or higher to use in your explanations.
