With reference to one sample t-test, the test statistics is given by the expression $t=\frac{17-18}{\frac{4.5}{\sqrt{48}}}$ then which of the following gives the correct set of order of values $\overline{x}, \mu_0$ , S and n ?

48, 17, 18, 4.5 17, 4.5, 48, 18 17, 18, 4.5, 48 18, 17, 48, 4.5

17, 18, 4.5, 48
