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 "Systolic blood pressure (SBP) "between "Male" and "Female"? Dataset for this can be retrieved on the given Excel. 1. What is the computed p-value for the given data on the SBP between Male and Female? Round it off to two decimal places. Then, answer (YES or NO) if there is a significant difference in the Systolic blood pressure (SBP) between Male and Female? 2. What is the computed Mean of Male on the given data for Systolic blood pressure (SBP)? Round it off to two decimal places. 3. What is the computed Standard Deviation of Female on the given data for Systolic blood pressure (SBP)? Round it off to two decimal places.

Consumer Reports uses a survey of readers to obtain customer satisfaction ratings for the nation's largest retailers (Consumer Reports, March 2012). Each survey respondent is asked to rate a specified retailer in terms of six factors: quality of products, selection, value, checkout efficiency, service, and store layout. An overall satisfaction score summarizes the rating for each respondent with 100 meaning the respondent is completely satisfied in terms of all six factors. Sample data representative of independent samples of size n1 = 25 for Target and size n2 = 30 for Walmart customers give the following customer satisfaction scores' sample averages: = 79 for Target and = 71 for Walmart. You formulate the null and alternative hypotheses to test whether there is a difference between the population mean customer satisfaction scores for the two retailers. Experience with the Consumer Reports satisfaction rating scale indicates that a population standard deviation of 12 is a reasonable…
