Question
The following table displays a frequency distribution for the number of crew members on each shuttle mission from April 12, 1981 to July 8, 2011.
| Crew Size | 2 | 4 | 5 | 6 | 7 | 8 |
| Frequency | 4 | 3 | 36 | 28 | 63 | 1 |
Let C = Crew Size
a) How many shuttle missions were there from April 12th, 1981 to July 8, 2011?
b) Create a probability distribution for the random variable C
| C = c | P(C = c) |
| 2 | |
| 4 | |
| 5 | |
| 6 | |
| 7 | |
| 8 | |
| 1.0000 |
Use your probability distribution to find:
c) P(C = 6) =
d) P(C is at least 4) =
e) P(C is no more than 7) =
f) P (4 ≤ C ≤ 7) =
g) P (2 < C ≤ 5) =
h) What is the expected crew size? E(C) =
