Question

When conducting research on color blindness in males, a researcher forms random groups with five males in each group. The random variable 0 0.669 x is the number of males in the group who have a form of color blindness. 0.278 Determine whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a probability 3 0.004 distribution is not given, idently the requirements that are not satisfied.0001 2 0.048 5 0.000 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, not every probability is between O arjd 1 inclusive. D. No, the sum of all the probabilities is not equal to 1. E. No, the random variable x is categorical instead of numerical. Find the mean of the random variable x. Select the correct choice below and, if necessary, ill in the answer box to complete your choice. ?A. ?·[..] male(s) (Round to one decimal place as needed.) O B. The table does not show a probability distribution. Find the standard deviation of the random variable x. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. male(s) (Round to one decimal place as needed.) O B. The table does not show a probability distribution.

Explanation / Answer

Solution:-

=> option A. yes,the table shows a probability distribution.

=> ? = 0.39

? = ?x?p(x) = (0*0.669)+(1*0.278)+(2*0.048)+(3*0.004)+(4*0.001)+(5*0.000)
= 0.39
= 0.4(rounded)

=> ? = 0.6082 = 0.6(rounded)

? = sqrt((?x^2?p(x))-?^2) = sqrt(3699/10000) = 0.6082
