The time (in number of days) until maturity of a certain variety of tomato plant is normally distributed with mean μ and standard deviation σ = 2.4. i select a simple random sample of four plants of this variety and measure the time until maturity. the sample yields = 65. you read on the package of seeds that these tomatoes reach maturity, on average, in 61 days. you want to test to see if your seeds are reaching maturity later than expected, which might indicate that your package of seeds is too old. the appropriate hypotheses are: h0: μ = 65, ha: μ < 65. h0: μ = 65, ha: μ > 65. h0: μ = 61, ha: μ > 61. h0: μ = 61, ha: μ < 61.

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)) =
