Need this solved along with the R code asap. Thank you very much in advance for the work. Right click and Open image in a new tab if it is too small to see. we wish to compare the expected values, μ× andWy of two independent normal populations, say X and Y, with known standard deviations ox-8.3 and ay-10.. we take a random sample of size 13 from X (XiX2. .Xi3) and a random sample of size 7 from Y (Y,Y) as follows: X: 0.54,-3.67, 1.41, 23.51, 20.77, 15.90, 16.70, 2.48, 12.27, 2.64, 22.12, 14.03, 17.80 Y: 21.22, 12.61, 15.04, 14.51, 10.91, -4.90, 22.71 we are interested in examining їх су дії the sample means o x and Y Xbar and Ybar respectively xbar and y ar realized values Assume a al distributions are normal computations. e r a)Calculate xbar b) Calculate the variance of Xbar c) Calculate ybar d) Calculate the variance of Ybar e) Calculate the variance of Xbar Ybar f) What is the critical value used for a 96% confidence interval for μΧ-ey? g) Create a 96% confidence interval for Ax-uy. h) what is the length of your 96% confidence interval for, x- y? | ) What would the p value have been if we used this data to test Hoix -Hy-0 against the alternative Ha 4 -Hy02 k) Copy your R script for the above into the text box here
