- chapter 8 question 11 suppose a simple random sample size of size n= 15 is obtained from a population with u=61 and q=14. The population must be normally distributed the sampling distribution of xbar is normal with ux= 61 and q = 14 over the square root of 15. B. P(xbar less than 64.6 assuming the normal model. assuming the normal model, p(x greater than or equal to 63.2Look at one of the marginal distributions described, and consider either value a success. Estimate the true population proportion for this value with a 95% confidence interval. (Hint: you may need to use the plus-four method if the sample size is too small.) We are now going to treat the sample as being two separate samples from two populations. One of the populations being compared is the population described in your conditional distribution (from problem 10). The other will be the rest of the sample. (An example is given below on how to form populations out of your Project 1 results.) Do these two populations have significantly different proportions successes? Use an appropriate significance test with.

Assuming the distribution of Xi is N(μi, σ2), i = 1, 2, 3, 4 and you test the null hypothesis H0: μ1 = μ2 = μ3 = μ4, using seven observations of each Xi, what would be the critical region for an alpha = 0.05 significance level?
- Problem 1 Assume body heights (inches) for the population of 8-year old boys are: X-N(My 51, 0y = 3). If we choose 100 boys at random, what is the probability that their average height exceeds 50 inches? In the class, we apply the statistical knowledge about sampling distribution of the sample mean, denoted by X; that is, 8~NAxox/n) to solve this question analytically Now, please solve this question numerically computationally. That is, you should use simulation to compute a numerical approximate of the probability. Submit your R code and output with a brief description or explanation of your solution (Hint: you should use the rmorm function instead of pnorm function in R.) Problem 2 Assume body heights (inches) for the population of 8-year old boys are: X-N(x = 51, 0x = 3). and body heights (inches) for the population of 8-year old girls are: Y-N(My = 53, ay = 3). If we randomly and independently choose 100 boys and 100 girls, what is the probability that the average height of the…Problem 10 : Independent random variables {U, X, W} have variances V[U] = 1, V[X] = 2, V[W] = 3.Let Y = 2U + 3X + 4W.
