Male Female 60 A factory hiring people to work on an assembly line gives job applicants a test of manual agility. This test counts how many strangely shaped pegs the applicant can fit into matching holes in a one-minute period. The table to the right summaries the data by gender of the job applicant. Assume that all conditions necessary for inference are met. Complete parts a through f. Number of subjects Pegs placed: Mean SD 60 19.66 18.29 2.81 3.92 a) Find 95% confidence intervals for the average number of pegs that males and females can each place. The 95% confidence interval for males is ( (Round to two decimal places as needed.)

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.
