Suppose a researcher examined a relationship between taking aspirin every day (yes/no) and the incidence of a heart attack (yes/no). the sample data showed that those taking aspirin had a lower chance of incidence of heart attack. a chi-square test on the data collected resulted in a p-value less than 0.0001. the data were collected in a well-designed randomized experiment. which of the following conclusions is appropriate
a. yes, because aspirin uses had a larger heart attack rate in both studies.
b. no, only researcher 1 can conclude this.
c. yes, because aspirin is known to reduce heart attacks
