Amanufacturer produces trinkets targeted to weigh 52 g. the weight of the trinkets is known to be normally distributed, but an engineer is concerned that the variation in the produced trinkets is larger than acceptable. in an attempt to estimate the variance, she selects n = 10 trinkets at random and weighs them. the sample yields a sample variance of 4 g2. define 90% ci for the variance.
