Question

5. (4 points) Determine whether the variable would best be modeled as continuous or discrete: The temperature of a greenhouse at a certain time of the day. Discrete B) Continuous Determine whether the following is a probability distribution. If not, identity the requirement that is not satisfied. (4 points) If a person is randomly selected from a certain town, the probability distribution for the number, x of siblings is as described in the accompanying table 6. 5 or more -0 (4 points) When Jon Snow was in the Wall he had some free time and flipped a coin one hundred times and he got the following: 7. What is the theoretical probability of getfing tails? A) 52% B)48% C)5% D)30% E)55%

Explanation / Answer

5) Option-B) continuous

6) to be a valid probability distribution, the sum of all probability must be equal to 1 and all value of probability must be between 0 and 1

Since P(5 or more) is negative this is not a valid probability distribution

7) P(tail) = 1/2 = 0.5 = 50%

Option-C) 50%
