4,12-Hi Wonderful Bartleby team,I need help with these 2 exercises from stats, please provide an answer for all the parts. (Thanks in advance). Refer to the accompanying data set and use the 30 screw lengths to construct a frequency distribution. Begin with a lower class limit of 3.470 in., and use a class width of .010 in. Thescrews were labeled as having a length of 3 1/2 in.E Click on icon to view the data.Data TableComplete the frequency distribution below.Length (in.)Frequency3.470 -Screw Lengths (inches)3.501 3.484 3.497 3.497 3.478 3.508 3.5093.492 3.5073.4983.509 3.4923.496 3.484 3.499 3.506 3.491 3.487 3.498 3.4783.496 3.513 3.503 3.507 3.489 3.489 3.509 3.496 3.505 3.495(Type integers or decimals rounded to the nearest thou Five males with an X-linked genetic disorder have one child each. TheP(x)0.033random variable x is the number of children among the five who inheritthe X-linked genetic disorder. Determine whether a probability distributionis given. If a probability distribution is given, find its mean and standarddeviation. If a probability distribution is not given, identify the requirementsthat are not satisfied.10.14820.3190.31940.1480.033.....Does the table show a probability distribution? Select all that apply.O A. Yes, the table shows a probability distribution.O B. No, the random variable x's number values are not associated with probabilities.O c. No, the sum of all the probabilities is not equal to 1.O D. No, the random variable x is categorical instead of numerical.O E. No, not every probability is between 0 and 1 inclusive.Find the mean of the random variable x.
