Write down the upper and lower quartiles. Upper Quartile = Lower Quartile = Question 3

15. यदि \( n(\mathrm{~A})=5 \) एवं \( n(\mathrm{~B})=2 \), तो \( n(\mathrm{~A} \cap \mathrm{~B}) \) में अधिकतम कितने सदस्य होंगे? \( \begin{array}{ll}\text { (1) } 2 & \text { (2) } 5 \\ \text { (3) } 7 & \text { (4) } 3\end{array} \)

A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 439 gram setting. Is there sufficient evidence at the 0.05 level that the bags are underfilled? Assume the population is normally distributed. State the null and alternative hypotheses for the above scehario. Answer 2 Points

4. Sospechamos que nuestro cromatógrafo está estropeado, y queremos determinar si los resultados que nos proporciona son lo suficientemente precisos. Para ello, realizamos una serie de 8 mediciones del contenido de una solución de referencia que, sabemos, contiene 90 ml . de un determinado compuesto. Los resultados que obtenemos en ml. son: \( 93.3 \quad 86.890 .490 .194 .9 \quad 91.6 \quad 92.3 \quad 96.5 \) Construir un intervalo de confianza al nivel de \( 95 \% \) para la media poblacional. ¿Qué conclusiones podemos realizar?

A carpenter is making doors that are 2058 millimeters tall. If the doors are too long they must be trimmed, and if they are too short they cannot be used. A sample of 11 doors is taken, and it is found that they have a mean of 2070 millimeters with a variance of 400 . Assume the population is normally distributed. is there evidence at the 0.05 level that the doors are too long and need to be trimmed? Step 2 of 6: Find the value of the test statistic. Round your answer to three decimal places.
