Problem 4 Three students use the same device to measure the density of the water in a salt lake. First student produced 7 measurements and have got x) =1.19, Sa) = 0.12. Second student produced 5 measurements and have got à 2) = 1.14, his record on sample variance were lost. The third one produced 10 measurements and have got $(3) = 0.10, his record on sample mean were lost. (a) Suggest the 95% confidence interval for the water density using all available information. (b) Formulate the assumptions you have made. 2
