Are you smarter than a second-grader? A random sample of 57 second-graders in a certain school district are given a standardized mathematics skills test. The sample mean score is X46, Assume the standard deviation of test scores is o 15. The nationwide average score on this test is 50, The school superintendent wants to know whether the second-graders in her school district have weaker math skills than the nationwide average. Use the a 0.05 level of significance and the P-value method with the TI-84 calculator. Part 1 of 4 State the appropriate null and alternate hypotheses.

In creating the null hypothesis for a hypothesis test for the standard deviation, it is wrong to write s = 30. Why is this so? ○ It just doesn't look and feel right. O Because my professor said so. O It should be the inequality sign, and not the equality sign. O Because hypothesis statements are about the popula- tion and not about the sample.

The 47 randomly observed intersections with cameras installed had an average of 5.9 accidents per year and the standard deviation was 1.08. What can be concluded at the a = 0.01 level of significance? a. For this study, we should use t-test for a population mean b. The null and alternative hypotheses would be: Ho: V = H₁: > 5.4 c.
