The probability of a Type I error (rejecting a true null hypothesis) is determined by the alpha level (α) set for the test, not by the choice between conducting an independent t-test or an ANOVA when comparing two samples. Both tests, when applied correctly and with the same α level, maintain the predefined probability of making a Type I error.
