Samples of plastic product were selected from a batch of material, and the tensile strength in kg was measured for three different time durations, with the following results. i. Estimate the variability due to time durations of tensile strength and the overall variability of the observations. (4 marks) ii. Is there a significance difference in the tensile strength due to different time durations? Use 1% significance level. (6 marks)
