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 =
5x = 2x + 9
3x = 9
x = 3
AB= 5(3)= 15
BC= 2(5) + 9= 10 + 9 = 19
AC= 15 + 19 = 34
4 is the number
