Country A exports $2 million worth of goods to country B and $16 million worth of goods to country C; country B exports $5 million worth of goods to country A and $13 million worth of goods to country C; and country C exports $12 million worth of goods to country A and $11 million worth of goods to country B.What are the total exports of countries A, B and C respectively?Total exports of Country A = $[a] million Total exports of Country B = $[b] millionTotal exports of Country C = $[c] millionWhat are the total imports of countries A, B and C respectively?Total imports of Country A = $[d] million Total imports of Country B = $[e] millionTotal imports of Country C = $[f] millionWhat are the net exports of countries A, B, & C respectively? Net exports of Country A = $[g] million Net exports of Country B = $[h] millionNet exports of Country C = $[i] millionCounty C is running a trade [j] (deficit, surplus).
A lоcаl mаrketing firm wаs wоndering if average mallgоers spent more than 25 dollars at the food court each trip. The firm surveyed its shoppers and received 10 responses. Using the results from the current survey and several previous surveys, the firm has decided to assume that the population standard deviation for the amount spent at the food court 11.2 dollars.The firm conducts a one-mean hypothesis at the 5% significance level, to test if the average amount spent at the food court is greater than 25 dollars.For this test: H0: μ=25; Ha: μ > 25The amount that the shoppers spent at the food court is given below. 25 43 28 37 26 46 11 26 20 31 What is the p-value?
