10 points Save Ans A study was done to determine if humans were capable of extrasensory perception (ESP). The study included 20,000 subjects from an SRS. The results were statistically significant at the .01 level and all statistical and design methods were properly used. Can the researchers reliably conclude that ESP does exist? O a. Yes, a P-value less than .01 is very small, which means the results must be valid. O b. No, a significance level much larger should be used. O c. No, the sample size is so large that the results may not be practically significant. O d. Yes, the results of the test of significance are valid as long as all methods are used properly
