- For the X random variable known to have a Fuzzy Normal Distribution the parameters belonging to the distribution are the triangle with u = (12,17,18) and &2 = (4,5,9) %3D are fuzzy numbers. For this random variable, the fuzzy probability of P [13,16.5] Calculate for a= 0.19Which is not an assumed characteristic of & in the population model y₁ = Be + B₁ X₁ + εi? Multiple Choice It is a random variable. It has zero mean. ○ It is a statistic. It is unobservable.The probability that data are entered incorrectly into a field in a database is 0.008. A data entry form has 24 fields, and errors occur independently for each field. The random variable X is the number of fields on the form with an error. Does X have a discrete uniform distribution? Why or why not?
