provide clear steps/explanations

use hypothesis-testing techniques to make inferences about the mean of two (2) different populations that are of interest to you. The goal is to test a claim based on a referenced value. Use a continuous variable (not a proportion). Find a reference (or use historical data) to what the expected value should be. Possibilities include: physical dimensions (e.g., diameter) or measurements (weight, resistance, voltage) of items such as coins, grocery items, resistors, 9-volt batteries; average finish place; batting averages; win percentages. Brainstorm & record ideas in your group for something you want to explore, then explain how you came to a decision (5 pts). Do one test (z-score) for a large sample (n > 40) and another test (t-test) for a different hypothesis for a different small sample (n s 40) - NOT a subset (total of 2 tests). Do 2 tests only! Do 1 of each 1-tail test 2-tail test Do 1 of each z-test (n > 40) t-test (n } Ho a = You should propose claims regarding the mean. Use an appropriate 1-tail test (which you should justify) for one test and a 2-tail test for the other test. Use one significance level, a (e.g., 0.01, 0.05, 0.10) for one test and a different a for the other test. Sketcha bell-shaped curve, clearly mark the "do not reject" and "reject" regions with the critical values for your z- and t-statistics (5 pts). Next, design and implement a sampling procedure to collect data for testing the claims. Finally, conduct hypothesis-testing analyses and make conclusions concerning the validity of the claims. Hypothesis testing should include both critical value and p-score analyses
