Identify the type of distribution described as binomial, chi-squared, discrete probability or a normal distribution AND briefly explain why you chose this distribution type.
a.)
| Number of platforms = x | 0 | 1 | 2 | 3 | 4 | 5 | 6 |
| P(X) | .03 | .06 | .19 | .14 | .36 | .17 | .06 |
b.) A completely fictitious poll of Easter basket recipients found that 78% of respondents disapproves of licorice (black) jelly beans. There were 576 people in the sample.
(A) It is discrete probability because the total sum of probability is equal to 1 and none of the probabilities is negative. We are provided with probabilities for each individual x value. So, it is discrete probability
(B) it is a binomial distribution because the probability of success is given as p = 0.78 with fixed number of trials n = 576
it is binomial because each trail is independent and number of trials is fixed
probability of failure is 1-p =1 -0.78 = 0.22
