ANSWER:Problem 7
Identifying Probability Distributions. In Exercises 7-14, determine whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied.
Genetic Disorder. Four males with an X linked genetic disorder have one child each. The random variable x is the number of children among the four who inherit the X linked genetic disorder.
Step by Step Solution
Step 1 of 2
Mean for a probability distribution is,
Mean,
Construct a table as shown below:
x |
P(x) |
x.P(x) |
0 |
0.0625 |
0 x 0.625 = 0 |
1 |
0.25 |
1 x 0.25 = 0.25 |
2 |
0.375 |
2 x 0.375 = 0.75 |
3 |
0.25 |
3 x 0.25 = 0.75 |
4 |
0.0625 |
4 x 0.0625 = 0.25 |
Calculate the mean using the table, ie;
