Una máquina produce piezas metálicas de forma cilíndrica. Se toma una muestra de piezas cuyos diámetros son \( \mathbf{1 . 0 1 , 0 . 9 7} \) \( \mathbf{1 . 0 3 , 1 . 0 4 , 0 . 9 9 , 0 . 9 8 , 0 . 9 9 , 1 . 0 1 \text { y } \mathbf { 1 . 0 3 }} \) centímetros. Utilice la prueba de kolmogorov - Smirnov con un nivel de significancia del \( \mathbf{5 \%} \) para probar la hipótesis de que el diámetro se distribuye en forma normal con una media de \( \mathbf{1 . 0 0} \) cm y una desviación estándar de \( \mathbf{0 . 0 2} \mathrm{cm} \).

\( 11,16,12,7,23,9,5,5 \) What is the median of the data? B. 10 D. 11 D. 18

Use this set of numbers to answer the question. \( \begin{array}{l}4,11,6,9,23,34,6,19 \\ \text { What is the median for this set of numbers? } \\ \text { A. } 6 \\ \text { B. } 10 \\ \text { D. } 14 \\ \text { D. } 16\end{array} \)

Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market. On January \( 31,2006,9 \) of the 30 stocks making up the DJIA increased in price (The Wall Street Journal, February 1, 2006). On the basis of this fact, a financial analyst claims we can assume that \( 30 \% \) of the stocks traded on the New York Stock Exchange (NYSE) went up the same day. A sample of 76 stocks traded on the NYSE that day showed that 10 went up. You are conducting a study to see if the proportion of stocks that went up is is significantly less than 0.3 . You use a significance level of \( \alpha=\ldots 2 \). What is the test statistic for this sample? Use \( \hat{p} \) rounded to 4 decimal places. (Report answer accurate to 4 decimal places.) test statistic =
