Not mak New Reco usmannd An article gave the following observations on maximum concrete pressure (kN/m²). 33.3 41.9 37.4 40.3 36.8 39.2 36.3 41.9 36.0 35.2 36.8 38.9 35.8 35.3 40.1 (a) Is it plausible that this sample was selected from a normal population distribution? Because of the number of observations, we ascertain that it is not plausible that this sample was taken from a normal population distribution. Using a normal probability plot, we ascertain that it is not plausible that this sample was taken from a normal population distribution. O Using a normal probability plot, we ascertain that it is plausible that this sample was taken from a normal population distribution. Because of the number of observations, we ascertain that it is plausible that this sample was taken from a normal population distribution. (b) Calculate an upper confidence bound with confidence level 95% for the population standard deviation of maximum pressure. (Round your answer to three decimal places.)
