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. $$\begin{array} { | l l l l l l l | } \hline 115 & 128 & 107 & 109 & 116 & 124 & 135 \\127 & 115 & 104 & 118 & 126 & 129 & 133 \\\hline\end{array}$$
