Suppose a random sample of 1,087 eighth graders found that 570 of them drank two or more caffeinated drinks a day. (a) State the 96% confidence interval. Round to four decimal places. (b) Interpret the 96% confidence interval. (c) Is there evidence to suggest that greater than 50% of eighth graders drink two or more caffeinated drinks in a day at the 5% level of significance?

what are the statements

step-by-step explanation:

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°
