"A manufacturer of shampoo claims that 27% of the shampoo users prefer brand X. To test this claim, a random sample of 53 participants are selected and asked what brand they prefer. If 8 of the 53 participants prefer brand X, what conclusion do we draw? Use a 0.05 level of significance." We are 100% sure that the claim is true. Empirical evidence suggest that it is safe to assume that the claim is true. "The claim is not supported by empirical evidence. In fact, it is less than the said proportion." "The claim is not supported by empirical evidence. In fact, it is greater than the said proportion."
