A consumer's organization is interested in determining the amount of variability in the price of one brand of camera. A survey of 25 retail outlets produces a mean and standard deviation of $380 and $20 respectively. 1. Compute the point estimate of the variance and the 95% confidence interval of the variance in the price of this brand of camera. Report your result (round to two decimal places). 2. What assumption did you have to make to obtain the confidence interval? F12 DD F11 F10
