If a scatter plot shows points that are closely clustered together, what can you infer about the correlation between the variables?

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

Arithmetic mean of three observations is 12 . The observations are such that they have a common difference of 2 between them. Compute median value. \( \begin{array}{ll}\text { (a) } 12 & \text { (b) } 10 \\ \text { (c) } 14 & \text { (d) } 36\end{array} \)

Bring out the median in this set of values: \( 1,2,2,4,8,9,3 \)

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: \( \begin{array}{ll}\text { i. No. of femaleworkers who are illiterate and unmarried. } \\ \text { ii. } \quad \text { No. of literate workers. who are unmarried males. } \\ \text { iii. } \quad \text { No. of married workers who are illiterate males. } \\ \text { iv. } \quad \text { No. of illiterate and unimarried male workers. }\end{array} \)
