Step-by-step explanation:
the graphs of and
are flipped: if the point
is on the graph of
, then the point
is on the graph of
.
Any points of intersection will satisfy . A point that satisfies this property must have the same x and y coordinate. (Think about it.) The only point on

Step-by-step explanation:
Given that the owner of a local nightclub has recently surveyed a random sample of n = 250 customers of the club.
(Right tailed test)
Sample size =
Sample mean = 30.45
Mean difference =
Sample std dev s = 5
Sample std error =
Test statistic = Mean diff/std error =
Since population std deviation is not know we use t test
p value =
