The null hypothesis for a t-test for a single mean is always about a population mean being equal to a specific value (μ = a). Choice A is a null hypothesis for a one-tailed t-test for a population mean being greater than a specific value. Choice B is a null hypothesis for an independent t-test for comparing means of two groups. Choice C is a null hypothesis for a two-sample t-test for comparing means of two groups.
