4) A: In the CTE lab, you used a nylon cable tie and measured its length before and after liquid nitrogen exposure. Assume that room temperature is 298K and liquid nitrogen temperature is 77K. Using the data provided below, calculate CTE, mean CTE, standard deviation and 95% confidence interval. (15 points) Initial Length (in) 5.870 4.977 6.120 5.225 4.560 4.885 Final Length (in) 5.668 4.812 6.010 5.115 4.435 4.780 Strain CTE B: Can you say with 95% certainty that exposing the cable tie to liquid nitrogen resulted in shrinking of your cable tie? Explain your answer (3 points)
