### Results of Case Control Study: Association Between High Blood Pressure and Stroke RiskThis study examines the association between high blood pressure (hypertension) and the risk of stroke in adult males. The data is presented in the table below:| Status | Cases of Stroke | Controls ||-----------------------|-----------------|----------|| High Blood Pressure | 300 | 200 || Normal Blood Pressure | 100 | 200 |**Interpretation Question:**11. What can you conclude if the Z score for these data is 7.0?- **A.** High blood pressure significantly decreased the risk of stroke.- **B.** High blood pressure significantly increased the risk of stroke.- **C.** Blood pressure had no effect on the risk of stroke.- **D.** None of the above.### Explanation:The table illustrates the difference in the number of stroke cases and controls between individuals with high blood pressure and those with normal blood pressure. A Z score of 7.0 suggests a statistically significant result. The interpretation options provide conclusions regarding the effect of high blood pressure on the risk of stroke.

Given data Z score for the data is 7.0 P(Z>7) = 0
