Explanation / Answer

16) From the given dot plot, we can see that the maximum value in the plot is 17 and the minimum value is 12

Therefore A is the correct answer here.

17) The expected value here is computed as:

E(X) = (1/50)*69 + (49/50)*(-3) = -1.56

Therefore c) -1.56 is the expected value here.

18) The probability of getting someone who is regular or heavy smoker here is computed as:

= ( Total number of regular or heavy smokers ) / Total frequency

= ( 87 + 15)/ 424

= 0.241

Therefore a) 0.241 is the required probability here.
