To determine whether high blood pressure affected whether a person had a stroke, a sample of 147 people who had had strokes are examined. In the sample, 35% had high blood pressure. If we were to test the hypothesis at the 10% level of significance that at least 31% of the people who have had strokes have had high blood pressure, what is the test statistic? (please round your answer to 2 decimal places)
