1. [Hint: Let Π = 0.02 as shown in the table for nofree premium channels.]
a. P(X< 3) =
b. P(X = 0) + P(X = 1) =
c. P(X > 4) = 1 - P(X ≤4) =
d. Calculate P(X ≥ 4) and compare it to your answer in c. Basically, the question is asking whether it is less likely or more likely that you will get four or more subscriptions in a sample of 50 prospective customers, given that the probability of a subscription is 0.02.] Explain your reasoning.
2. [Hint: Let Π = 0.06 as shown in the table for two free premium channels.]
a. P(X < 3) =
b. P(X = 0) + P(X = 1)
c. P(X > 4) = 1 - P(X ≤ 4).
d. [Hint: This question is asking you to compare the likelihood of your getting 4 or more subscribers in a sample of 50 when the probability of a subscription has risen from 0.02 to 0.06.] Talk about the comparison of probabilities in your explanation.
3. Study the table given and answer the question after you calculate four possibilities.
a. 1 free premium channel, 5 subscriptions, Π = 0.04,
P(X ≥ 5) =
b. 3 free premium channels, 6 subscriptions, Π = 0.07,
P(X ≥ 6) =
3. [continued]
c. 4 free premium channels, 6 subscriptions, Π = 0.08,
P(X ≥ 6) =
d. (5 points) 5 free premium channels, 7 subscriptions, Π = 0.085,
P(X ≥ 7) =
e. Given all the evidence that you have collected from all your surveys of 50 prospective customers, answer the question will full explanation.
