How heavy a load (in pounds) is needed to pull apart pieces of Douglas fir 4 inches long and 1.5 inches square? The file wood.csv contains the data collected from students doing a laboratory exercise. It has only one variable called "load". a) [1 point] Compute the mean and standard deviation (sd) of the data. b) [4 points] Perform the following steps: 1. Randomly select n = 5 (no need to set a random seed) from the data to form a sample; 2. Compute the sample mean of the selected sample. 3. Repeat the procedure above for 2500 times to get a sequence of sample means. c) [3 points] Repeat part d) by changing n to 50, 500, 5000 to produce three extra sequences. Draw a histogram for each of the sequences (with a fitted density) and overlay them together using different colors. d) [3 points] From the histograms in the previous two parts, can you spot any pattern in the shapes of the histograms as n increases? Can you recall a related theorem we mentioned in course.

I DONT NEED THE REAL ANSWER WITH THE DATA, I JUST WANTED TO KNOW WHAT CODES SHOULD I USE AND I CAN PLUG IN THE DATA.
