0.0735,0.0179,0.7026
Step-by-step explanation:
Given that a simple random sample of size nequals 49 is obtained from a population with mu equals 78 and sigma equals 28.
Sample size = 49
Population mean = 78
Population std deviation = 28
Std error of sample mean =
a) : N(78, 4)
b)
(by converting to Z and finding value from Z table)
c) P (x overbar less than or equals 69.6 )
=
d) P (75.8 less than x overbar less than 88 )
=
You are trying to find what x to put into f(x) to get out 46. To do this, solve the following equation.
Therefore x = 7 or x = -7
-7, 7
Therefore x = 7 or x = -7
-7, 7
