James and Margaret grow watermelons. Margaret claims her watermelons are heavier than James's watermelons. $40$ sample has been taken from both.
James: mean $7.3$ variance $0.4$ Margaret mean $11.3$ variance $2.8$
which test statistic should i use? I'm looking at 2 sample proportion test right now . and how should I make the assumptions?
$H_0= J\geq M$
$H_a= M < J $
