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.

A popular theory is that presidential candidates have an advantage if they are taller than their main opponents. Listed are heights (in centimeters) of randomly selected presidents along with the heights of their main opponents. Complete parts (a) and (b) below.

Identify the P-value P-value = 0.286 (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? Since the P-value is greater than the significance level, fail to reject the null hypothesis. There is not sufficient evidence to support the claim that presidents tend to be taller than their opponents. b. Construct the confidence interval that could be used for the hypothesis test described in part (a). What feature of the confidence interval leads to the same conclusion reached in part (a)?
