- Pls answer completeleya) X is a normally distributed variable with mean u = 30 and standard deviation o = 4. Find i) P(x 21) iii) P(30part d,e,f) Determine the mean (μ!" ) of sample means distribution (x#-distribution).b) Determine the standard deviation (standard error) (σ!" ) of sample means distribution(x#-distribution).c) Draw a Normal (bell-shaped) graph for sample means distribution (x#-distribution) byhand on a paper showing x and y axes without any values marked on them. However,label the values of mean and standard deviation as described below. The adult male heights in a country vary normally with mean of 70 inches and standarddeviation of 4 inches. We draw many samples of size 100 from the above populationusing repeated random sampling and record the mean height for each sample to constitutea sample means distribution (x#-distribution). Do the above for the distribution.3. The frequency distribution of a measurable characteristic varying between 0 and 2 is represented by the following : f (x) = x³, = (2 – x)³, 03.- It has been found that the waiting time to obtain a table in a cafe during rush hour has a normal distribution with a mean of 130.7 min. and a standard deviation of 12.5 min. How long do people have to wait to be given a table with the following probability?a) P (X ≥ Xo) = 0.83.b) P (X ≥ Xo) = 0.12c) P (X ≤ Xo) = 0.92d) P (X ≤ Xo) = 0.0710. a.) Find the z-value such that 80 percent of the area under the standard normal curve lies between -z and z. b). Find the z value if the normal curve area to the right of z is 0.6449. is from N(0,1) de in a cmall town at California is 0.2 everyday, what is the5. The distribution of male weight in the United States has a standard deviation of roughly o = 25 lbs. The average weight u varies from state to state. Suppose you randomly select 100 males in Louisiana and ask their weights, and you compute the average weight Xn of the n = 100 males. a) Assuming that the standard deviation of weight in Louisiana is 25 lbs, what does the Central Limit Theorem tell you the (approximate) distribution of X will be?2.5. Let N be a random variable with distribution function 0 if <0 F(2) = 〈a,2 if 0 < x < 1 Find P{1,4 < X < 5), P12 < X < .8}, and P(X = 1/2).Assume X is normally distributed with a mean of 13 and a standard deviation of 2. Determine the value for x that solves each of the following. Round the answers to 2 decimal places. a) P(X> x) = 0.5. x = b) P(X > x) = 0.95. X = c) P(x < X < 13) = 0.2. X = i d) P(-x < X 13 < x) = 0.95. X = i e) P(-x < X - 13 < x) = 0.99. x = i3.4 Solve the below problem: Let Y, and Y, have a bivariate normal distribution: 2. 1. 2. Y2-H2 exp 2no,02y1-p2 2(1-p2) {.
