A researcher conducts 20 tests of statistical significance,one for each independent variable,wita.05 significance level.Only one test yields a probability value that is not greater than .05.What can we infer about the latter test?
A) The probability of committing a Type I error in rejecting the null hypothesis is .05.
B) It is a statistically significant predictor of the dependent variable.
C) Because so many tests were conducted, the probability of committing a Type I error is greater than .05.
D) Because so many tests were conducted, the probability of committing a Type I error is much smaller than .001.
