Adairy scientist is testing a new feed additive. she chooses 13 cows at random from a large population of cows. she randomly assigns nold = 8 to get the old diet, and nnew = 5 to get the new diet including the additive. the cows are housed in 13 separated pens and each gets separate feed, with or without additive as appropriate. after two weeks, she picks a day and milks each cow using standard procedures and records the milk produced in pounds. the data are below: old diet: 43, 51, 44, 47, 38, 46, 40, 35new diet: 47, 75, 85, 100, 58let µnew and µold be the population mean milk productions for the new and old diets, respectively. she wishes to test: h0 : µnew vs µold = 0 vs. ha : µnew vs µold 6= 0, using α = 0.05.(a) are the two populations paired or independent?
x=3 over 8
simplify 4^2 to 16, divide both sides by 16, then simplify 6 over 16
answer: she can buy 5 goldfish.
step-by-step explanation: if you divide the amount of money she has to spend by the cost of the goldfish;
$11/5 = 5.5
since she can’t buy 5 and a half goldfish, she can only buy 5.
