Vai of ce oloqure regresio lnec? slope of the least-square regression line. y-intercept of the least-square regression line. variable value. to do so. [A] An influential observation is an observation that significantly affects only on the value of the B] An infuential observation is an observation that significantly affects only on the value of the C] Influential observations typically exist when the point is an outlier relative to its response ID) Influential observations are typically outliers and can be removed only if there is justification E] None of the above. 6. Histogram can be used to identify the distributional shape of [A] ordinal data. B] nominal data. [C] qualitative data. ID] continuous data. E] None of the above. 7. A and B are two events such that P(A/B)0.3, P(BA) 0.4. Which of the following is correct? [A] P(AUB) = 1.45P(8) [B] A and B are not mutually exclusive. [C] If A and B are independent then P(AUB) -0.58 [D] All of the above are true. E] None of the above. 8. If the mean of the following probability distribution is 2 then the value of p is 12 3 A) 0.3 (B] 0.4 [C]0.5 D] 0.6 [E] 0.7

Explanation / Answer

5) option A is correct. Slope must be Significant in least square line so that it can be used

6) Qualitative Data

7) From given

P( A and B) = 0.3P(B) and P(A and B) = 4P(A)

So, 0.3P(B) = 4P(A)

P( A or B) = P(A)+P(B)-P(A and B)

= 3/4P(B)+P(B)-0.3P(B)

= 1.45P(B)

So, option A is correct
