When conducting research on color blindness in males, a researcher forms random groups with five males in each group. The random variable x is the number of males in the group who have a form of color blindness. 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.

Question
Transcribed Image Text:When conducting research on color blindness in males, a researcher
forms random groups with five males in each group. The random variable
x is the number of males in the group who have a form of color blindness.
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.
Does the table show a probability distribution? Select all that apply.
A. Yes, the table shows a probability distribution.
B. No, the random variable x's number values are not associated with probabilities.
C. No, the random variable x is categorical instead of numerical.
D. No, the sum of all the probabilities is not equal to 1.
E. No, not every probability is between 0 and 1 inclusive.
Find the mean of the random variable x. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
