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 1 . randomly selected college students are listed below. Use a $0.10$ significance level to test the claim that the standa deviation of $\mathrm { IQ }$ scores of college students is less than 15.
$\begin{array} { l l l l l l l } 115 & 128 & 107 & 109 & 116 & 124 & 135 \ 127 & 115 & 104 & 118 & 126 & 129 & 133 \end{array}$
