The melting point of each of 16 samples of a certain brand of hydrogenated vegetable oil was determined, resulting in x = 54.32. Assuming that the distribution of melting point is normal with = 1.20 (a) Test the hypothesis H0 : = 55 versus H : ≠ 55 using = 0.01 (b)If a level 0.01 test is used, what is (54), the probability of a type II error when = 54? (c) What value of is necessary to ensure that 54 = 0.1 when = 0.01

Create a graph for the demand for starfish using the following data table: quantity/price of starfish quantity (x axis) of starfish in dozens price (y axis) of starfish per dozen 0 8 2 6 3 5 5 2 7 1 9 0 is the relationship between the price of starfish and the quantity demanded inverse or direct? why? how many dozens of starfish are demanded at a price of five? calculate the slope of the line between the prices of 6 (quantity of 2) and 1 (quantity of 7) per dozen. describe the line when there is a direct relationship between price and quantity.
