DevoreStat9 7E.046 An article gave the following observations on maximum concrete pressure (kN/m). 33.3 41.8 37.4 40.3 36.8 39.2 36.2 41.9 36.0 35.2 36.8 38.9 35.8 35.3 40.2 (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 plausible that this sample was taken from a normal population distribution. 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 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. (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.)

A random sample of 108 lightning flashes in a certain region resulted in a sample average radar echo duration of 0.81 sec and a sample standard deviation of 0.43 sec. Calculate a 99% (two-sided) confidence interval for the true average echo duration u. (Round your answers to two decimal places.)
