Test data on the bending strength of construction wood poles of various diameter are
presented below assuming the same length. Kip- 1000 lbf. Using the following data with 2nd
order Newton polynomial interpolation, we want to determine the strength of the material for
x=4.9 in. Which data point will be used as x? After you found x0, enter the value of x-xo in
the solution. Answer shall be in one decimal place.

- You are provided with data that includes all 50 states of the United States. Your task is to draw a sample of: o 20 States using Random Sampling (2 points: 1 for random number generation; 1 for random sample) o 10 States using Systematic Sampling (4 points: 1 for random numbers generation; 1 for random sample different from the previous answer; 1 for correct K value calculation table; 1 for correct sample drawn by using systematic sampling) (For systematic sampling, do not use the original data directly. Instead, first randomize the data, and then use the randomized dataset to draw your sample. Furthermore, do not use the random list previously generated, instead, generate a new random sample for this part. For more details, please see the snapshot provided at the end.)
