"A manufacturer of shampoo claims that 86% of the shampoo users prefer brand X. To test this claim, a random sample of 42 participants are selected and asked what brand they prefer. If 30 of the 42 participants prefer brand X, what conclusion do we draw? Use a 0.1 level of significance." A "The claim is not supported by empirical evidence. In fact, it is less than the said proportion." B) "The claim is not supported by empirical evidence. In fact, it is greater than the said proportion." C Empirical evidence suggest that it is safe to assume that the claim is true. D We are 100% sure that the claim is true.
