11. To test whether aspirin is effective in preventing heart attacks, 902 patients were given aspirin and 802 were not given aspirin. Data on the number of heart attacks was recorded as follows: ASPIRIN: X1 = 152 n1=902 P 1 =.168 NO ASPIRIN: X2 = 162 n2=802 P 2=.201 Assume Case 1. Using Excel and a 1% level of significance, is the percentage of heart attacks significantly less with patients who took aspirin? Use printscreen to show the results, indicate the relevant data on the Excel output, and state the conclusion
