One-Way ANOVA + Tukey Post-Hoc Comparisons An instructor is comparing the test scores of students who completed the same course using three different curricula: one with an expensive textbook, one with an open (i.e., free) textbook, and one with no textbook. Use Minitab Express to compute the mean and standard deviation for the TestScore variable for each of the three curricula separately (Descriptive Statistics > Variable = TestScore and Group variable = Curriculum). Include your Minitab Express output and to clearly identify your final answer from the output

A. Use Minitab Express to conduct a one-way ANOVA to compare the test scores of the three curriculum groups. Use the five step hypothesis testing procedure outlined below. Remember to copy + paste all relevant Minitab Express output and to clearly identify your final answers from the output.

Step 1: State hypotheses and check assumptions.

Step 2: Compute the test statistic.

Step 3: Determine the p-value

Step 4: Decide to reject or fail to reject the null hypothesis.

Step 5: State a real-world conclusion. I am 95% confident that ...

B. Use Minitab Express to conduct Tukey simultaneous tests for differences in means. Remember to include all relevant output. Clearly state which pairs are significantly different and which pairs are not significantly different.

C. Write a few sentences summarizing the results of your one-way ANOVA and Tukey tests for a general audience. Imagine that you are explaining your results to someone with little or no knowledge of statistics.

Which TWO statements about Gauss's Law of electrostatics are INCORRECT in the following five options? O The electric field that is normal to the Gaussian surface should not be taken into account A larger Gaussian surface will increase the magnitude of the total electric flux in a charge-free region. O) If the medium enclosed by the Gaussian surface has a higher permittivity, the total flux of the electric displacement vector will not change. The total electric flux going through the Gaussian surface is determined by the enclosed charges and the medium permittivity. O The Gaussian surface must be a closed surface.A Gaussian (closed) surface is drawn around a region of space. There are 25 field lines leaving the Gaussian surface, and 35 field lines entering the Gaussian surface. True or False: The region of space inside the Gaussian surface must contain some positive charge. True False
