Imagine you are standing on a skateboard, initially motionless. You throw a medicine ball horizontally while on the skateboard and as a result you roll backward.

1. Model this situation by creating a complete momentum chart with the initial momentum at a time just before you throw the ball and the final momentum at a time just after letting go.

2. Consider the same scenario but use an interval with the final state chosen after the motion of the throw, but before the ball left your hands: Would you roll backward, forward, or remain in the same spot at that moment? Create a complete momentum chart to argue your case, and write out the reasoning for your answer.

Plz don't miss the momentum chart: WHAT SHOULD INCLUDE IN MOMENTUM CHART

Preliminary data analyses indicates that use of a paired Wilcoxon signed-rank test is reasonable. Perform the hypothesis test by using a paired Wilcoxon signed-rank test. Assume that the null hypothesis is Ho:u1=u2

In a study of the effectiveness of physical exercise in weight reduction, 12 subjects followed a program of physical exercise for two months. Their weights (in pounds) before and after this program are shown in the following table.

  

  

At the 5% significance level, do the data provide sufficient evidence to conclude that the exercise program is effective in reducing weight?

A company claims that its new drug is effective is lowering blood pressure. To test this claim, an independent clinic tested the drug on 6 volunteers. Below are the blood pressures before and after taking the new drug.

(a) What tailed test is this? (i.e., RIGHT, LEFT, or TWO-TAILED?)

(b) What is the value of the "Test Statistic"?   

(c) What is the critical value(s)? Use α=0.05.

(d) What is the P-value?

(e) Do you "Reject" or "Fail to Reject" the Null Hypothesis?

(f) Is the company justified in its claim? [Use the Summary Table provided in class]

A researcher wanted to see if high doses of cinnamon could lower hemoglobin A1c levels in prediabetic patients. A1c levels were measured in 8 randomly selected subjects before they began a treatment plan involving cinnamon supplements. Then their A1c levels were measured again 6 months after they had been adhering to the supplementation. Here is the data. Does the cinnamon supplement appear to be effective in lowering the A1c levels? Test the claim at the 1% significance level.

The next 7 questions are related to the titration of 60.0 mL of a 0.0250 M Zn2+ solution with 0.0600 M EDTA in a solution buffered at pH 11. Assume that the temperature is 25 oC and that the formation constant for Zn2+ is 3.13 x 1016 at this temperature.

How many mmols of Zn2+ are present in the solution before the titration begins?

What volume of the EDTA solution is needed to reach the equivalence point?

What is the conditional formation constant for Zn at this pH?

What is the pZn of the analyte solution before the titration begins?

What is the pZn of the solution after 15 mL of titrant have been added?

What is the pZn at the equivalence point of the titration?

What is the pZn of the solution after 30 mL of titrant have been added?

In a test of the effectiveness of garlic for lowering​ cholesterol, 36 subjects were treated with raw garlic. Cholesterol levels were measured before and after the treatment. The changes​ (before minus​ after) in their levels of LDL cholesterol​ (in mg/dL) have a mean of 0.7 and a standard deviation of 20.1. Use a 0.10 significance level to test the claim that with garlic​ treatment, the mean change in LDL cholesterol is greater than 0. What do the results suggest about the effectiveness of the garlic​ treatment? Assume that a simple random sample has been selected. Identify the null and alternative​ hypotheses, test​ statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative​ hypotheses?

Determine the test statistic.

Determine the​ P-value.
