Essay

Use the traditional method to test the given hypothesis. Assume that the population is normally distributed and
that the sample has been randomly selected. For randomly selected adults, IQ scores are normally distributed
with a standard deviation of 15. The scores of 14 randomly selected college students are listed below. Use a 0.10
significance level to test the claim that the standard deviation of IQ scores of college students is less than 15. Round
the sample standard deviation to three decimal places. $$\begin{array} { | l l l l l l l | } \hline 115 & 128 & 107 & 109 & 116 & 124 & 135 \\127 & 115 & 104 & 118 & 126 & 129 & 133 \\\hline\end{array}$$
