4. ระยะเวลา (นาที) ที่ใช้ในการเดินทางไปสอนนักเรียน ตามห้องเรียนทั้งหมด 6 ห้องตังนี้ \( \begin{array}{rlllll}8 & 12 & 13 & 14 & 6 & 11\end{array} \) มัธย์านของข้อมูลข้างต้นเป็นเท่าใด \( \begin{array}{llll}16.5 & \text { นาที } & \text { ข. } 15.5 & \text { นาที } \\ \text { ค. } 14.5 & \text { นาที } & \text { ง. }\end{array} \)

Cite as características que um bom diagrama de dispersão deve ter para facilitar a interpretação dos dados.

1- Put the ( \( \vee \) ) mark against the statement if it is true and \( (x) \) if it false (10 POIN 1) The number of chlldren in a family is a qualitative data. 2) the mode is always found 3) For any two events \( A \) and \( B \) we must have \( P(A \cup B)=P(A)+P(B) \) 4) The sum of relative frequencies is 1 5) If the events \( A \& B \) are independent then \( \bar{A} \& \bar{B} \) are dependent 6) If the mean >median \( > \) mod the curve is skew from right. 7) The number of different permutations of word \( M I S S I S S I P P I \) is 3400 8) If the mode \( =24 \) and mean \( =60 \) then median \( =50 \). 9) In combination order is not important. 10) If \( X \) is a continuous random variable, then \( P(X=5)=0 \)

How do you identify the relationship between two variables in a scatter plot?

Calculate the mode of this given data \( 2,3,2,1,4,4,1,1,3,2,5,3,5,1,5,1,4 \), \( 2,3,0,4,1,0,3,5,2,5,0,4,1,4,0,5,2,3,0,4,1,2 \)

1. There are 330 workers in a factory. Out of them, 100 are females, 10 are literate and 100 are married. Moreover, 10 females are literate an married, 20 females are literate and unmarried, 25 married females ar illiterate and 5 "married and literates are males. By drawing the necessar venn-diagram, you are required to find: \( \begin{array}{ll}\text { i. No. of femaleworkers who are illiterate and unmarried. } \\ \text { ii. } \quad \text { No. of literate workers. who are unmarried males. } \\ \text { iii. } \quad \text { No. of married workers who are illiterate males. } \\ \text { iv. } \quad \text { No. of illiterate and unimarried male workers. }\end{array} \)
