Question

What probability value would be needed to complete the following probability distribution? P") 0.56 0.17 0. 12 0.25 0.15 0 0.25 0.09 o There is no value that would make this a probability distribution QUESTION 2 Continuous random variables are obtained from data that can be measured rather than counted . True False QUESTION 3 What probability value would be needed to complete the following probability distribution? P(x) 0.10 0.26 0.14 0.26 0.12 0 0.24 O 48 There is no value that would make this a probability distribution QUES TION 4 What of the following pairs of probability values would complete the following probability distribution? P(x) O 14 0.18 P1 P2 0. 17 0. 18 P1 = 0.09. P2 = 0.46 P1 = -0.11 p2 = 0.44 p1 = 0.33, P2= 0.28 P1= 0.05. P2 = 0.28

Explanation / Answer

1) sum of probabilities must be 1

Let the missing probability be X

0.56+0.17+0.12+0.25+X = 1

X = -0.1

x value cannot be negative

These is no value that would make this a probability distribution

2) True

When we count, we get discrete data

3) Let the missing probability be X

0.1 + 0.26+ 0.14 + X + 0.26 = 1

X = 0.24

4) 0.14 + 0.18 + P1 + P2 + 0.17 + 0.18 = 1

P1 + P2 = 0.33

P1 and P2 cannot be negative, so the only option that satifies the condition is P1 = 0.05, P2 = 0.28
