(a) In order to estimate the thermal expansion of a metal, measurements of the change of length for a known change of temperature are taken by a group of students. A sample random of size 36 is drawn with mean of 15.32 x 10-4 m °C-1 and a standard deviation of 0.12 x 10-4 m °C-¹. Determine the 99% confidence interval for population mean of the thermal expansion, correct to two decimal places. [It is given that: Z0.01 = 2.58]
