Aresearcher randomly selects and measures the volumes of the contents of 1212 bottles of cough syrup. assume the sample is taken from a normally distributed population. the 9090% confidence interval for the population standard deviation sigmaσ is (0.02490.0249,0.04420.0442). the population standard deviation of the volumes of the bottles' contents should be less than 0.0410.041 fluid ounce. does the confidence interval for sigmaσ suggest that the variation in the volumes of the bottles' contents is at an acceptable level? explain your reasoning.

Someone answer asap for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
