14..)   A study of 3000 patients was conducted to determine if taking aspirins daily reduces the chances of a heart attack. Half of the patients were given a regular dose of aspirin (1) while the other half was given placebos (2). Three years later, 1.8% of those who took aspirins suffered heart attacks, while 3.4% of those who took placebos suffered heart attacks. At 0.01 significance level, is there sufficient evidence to conclude that the aspirin can reduce the chance of heart attacks?    (d) What is the value of the test statistic? Round to the 2nd decimal place.   (e) What is the p-value? Round to the 3rd decimal place.  (f)  At 0.01 significance level, is there sufficient evidence to conclude that the aspirin can reduce the chance of heart attacks?  Yes or No
