LORETTA STONE 1/14 Question 2 of 8, Step 2 of 2 Correct Steve believes that his wife's cell phone battery does not last as long as his cell phone battery. On seven different occasions, he measured the length of time his cell phone battery lasted and calculated that the mean was 16.3 hours with a standard deviation of 5.5 hours. He measured the length of time his wife's cell phone battery lasted on eleven different occasions and calculated a mean of 21.6 hours with a standard deviation of 2.7 hours. Assume that the population variances are the same. Let Population 1 be the battery life of Steve's cell phone and Population 2 be the battery life of his wife's cell phone.

INSTRUCTION: Perform an appropriate statistical test using the dataset (Sheet name: Raw Data) if a researcher would like to determine if there is a significant difference in the "Serum Creatinine (SCr)" between ages "Under 60" and "60 and Above"? Dataset for this can be retrieved on the given Excel. 1. What is the computed p-value for the given data on the Serum Creatinine (SCr) between "Under 60" and "60 and Above"? Round it off to two decimal places. Then, answer (YES or NO) if there is a significant difference in the Serum Creatinine (SCr) between "Under 60" and "60 and Above"? 2. What is the computed Mean of "Under 60" on the given data for Serum Creatinine (SCr)? Round it off to two decimal places. 3. What is the computed Standard Error of "60 and Above" on the given data for Serum Creatinine (SCr)? Round it off to two decimal places.
