(a)
To find: The expected number of upsets
(a)
Answer to Problem 15PPS
The expected number of upsets is 4
Explanation of Solution
Given;
The given data is as follows:
Calculation:
The expected value is calculated as,
Round off the value to the nearest integer.
Thus, the expected number of upsets is 4
(b)
To find: The standard deviation.
(b)
Answer to Problem 15PPS
The standard deviation is 1.90
Explanation of Solution
The formula for the variance is,
The formula for the standard deviation is,
Table 1
Thus, the standard deviation is 1.90
(c)
To find: The relative frequency table for 50 trials.
(c)
Answer to Problem 15PPS
The relative frequency table for 50 trials is shown in Table 2.
Explanation of Solution
Draw the possible table for 50 trials.
Prize, X | Frequency | P(X) |
0 | 1 | 0.02 |
1 | 2 | 0.04 |
2 | 1 | 0.02 |
3 | 8 | 0.16 |
4 | 9 | 0.18 |
5 | 20 | 0.40 |
6 | 7 | 0.14 |
7 | 2 | 0.04 |
8 | 0 | 0.00 |
Table 2
Thus, the relative frequency table for 50 trials is shown in Table 2.
(d)
To find: The graph for experimental probability distribution.
(d)
Answer to Problem 15PPS
The graph for experimental probability distribution is shown in figure 1.
Explanation of Solution
From Table (2), the graph is plotted as,
Figure 1
Thus, the graph for experimental probability distribution is shown in figure 1.
