QUESTION 12
In the video game Animal Crossing: New Horizons, you can catch and sell both fish and sea creatures. Alison
learns that sea creatures sell for a mean of u = 3,345 bells with a standard deviation of o = 3,684 bells ("bells"
is the currency in the game). Alison suspects that fish will sell for more money than sea creatures will, so she
decides to conduct a hypothesis test at the a = 0.01 level with
%3D
%3D
Họ: µ= 3,345 bells
H1: p > 3,345 bells
She finds a sample of 64 fish and computes their mean price to be 3,527 bells.
a. Determine the standard error to the nearest thousandth.
Ox =
