It is believed that the mean height of high school students who play basketball on the school team is 73 inches with a standard deviation of 1.8 inches. A random sample of 40 players is chosen. The sample mean was 71 inches, and the sample standard deviation was 1.5 years. Do the data support the claim that the mean height is less than 73 inches? The p-value is almost zero. State the null and alternative hypotheses and interpret the p-value. State the true st deviation(sigma) Sample size=? Sample mean=? Type of test=(z-test, t-test or 1-prop-z-test) P- value=? Reject H0 or do not Reject H0 Conclusion of what the sample data supports?

In a certain high school, uniforms are optional. A study shows that high school students who wear uniforms have a lower grade average than students who don't wear uniforms. From this study, the school administration claims that they should not require the students to wear uniforms because that is the cause of the lowering grades. Another possible explanation is that students who wear uniforms are poorer than the students who don't wear uniforms and the economic situation of their parents...

Ten years ago the mean Math SAT score of all high school students who took the test in a small high school was 490, with a standard deviation of 80. This year, a researcher took the scores of a random sample of 16 students in the high school who took the SAT. The mean score of these 16 students is (X bar) = 530. In addition, the researcher assumes that the population standard deviation continues to be σ = 80....
