Asimple random sample of size nequals79 is obtained from a population that is skewed left with muequals59 and sigmaequals8. does the population need to be normally distributed for the sampling distribution of x overbar to be approximately normally distributed? why? what is the sampling distribution of x overbar?

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
