Explanation / Answer

Ans:

1)Quantitative continuous

option b is correct.

2)P(A and B)=P(A)*P(B)=0.4*0.3=0.12

option b is correct.

3)z score=(74-50)/10=+2.4

option c is correct.

4)Largest=160

Smallest=70

Class interval=(160-70)/6=90/6=15

Option a is correct.

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

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

P(A and B)=0.84+0.76-0.9=0.7

Option c is correct.
