A researcher would like to know if a vegan diet will lower cholesterol. A sample of n = 9 adults is obtained, and each has their cholesterol levels measured. Each participant then goes on a strict vegan diet for the next 45 days and cholesterol levels are measured again after that. Average total cholesterol dropped by MD = 14 points after the vegan diet with SS = 1152 for the difference scores. 1. What is the sample standard deviation?  Report to one decimal. 2. What is the value for the estimated standard error? Report to one decimal. 3. What if the observed t value from the example above?  Answer to two decimals. 4. How many degrees of freedom are in the current study?  Report a whole number no decimals.

It takes an average of 11.6 minutes for blood to begin clotting after an injury. An EMT wants to see if the average will change if the patient is immediately told the truth about the injury. The EMT randomly selected 40 injured patients to immediately tell the truth about the injury and noticed that they averaged 12.1 minutes for their blood to begin clotting after their injury. Their standard deviation was 1.76 minutes. What can be concluded at the the a = 0.05 level of significance? For this study, we should use Select an answer The null and alternative hypotheses would be: Ho: ? Select an answer H₁: ? Select an answer The test statistic ? ✓ = The p-value = The p-value is ? ✓ a Based on this, we should [Select an answer the null hypothesis. Thus, the final conclusion is that ... (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) O The data suggest the population mean is significantly different from 11.6 at a = 0.05, so there is statistically…
