Aproducer of fine chocolates believes that the sales of two varieties of truffles differ significantly during the holiday season. the first variety is milk chocolate while the second is milk chocolate filled with mint. it is reasonable to assume that truffle sales are normally distributed with unknown but equal population variances. two independent samples of 18 observations each are collected for the holiday period. a sample mean of 12 million milk chocolate truffles sold with a sample standard deviation of 2.5 million. a sample mean of 13 million truffles filled with mint sold with a sample standard deviation of 2.3 million. use milk chocolate as population 1 and mint chocolate as population 2. assuming the population variances are equal, which of the following is the value of the appropriate test statistic?

Someone answer this asap rn 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)) =
