Express the null and alternative hypotheses in symbolic form for this claim: the mean weight of female dancers in a local modern dance company is less than 140 lbs. Note that the mean weight in the sample taken is 135 lbs. H 0 : μ H 1 : μ Use the following codes to enter the following symbols: ≥ enter >= ≤ enter <= ≠ enter !=

To test the null hypothesis "The mean weight for adult males equals 160 lb" against the alternative, "The mean weight for adult males exceeds 160 lb," the weights of 16 males were obtained: $$\begin{array}{llllllll}\hline 173 & 178 & 145 & 146 & 157 & 175 & 173 & 137 \\152 & 171 & 163 & 170 & 135 & 159 & 199 & 131 \\\hline\end{array}$$ Assume normality and verify the results shown on the following MINITAB analysis by calculating the values yourself.
