Answer:
(a) The sampling distribution of
= Population mean = 79
(b) P (
greater than 81.2 ) = 0.1357
(c) P (
less than or equals 74.4 ) = .0107
(d) P (77.6 less than
less than 83.2 ) = .7401
Step-by-step explanation:
Given -
Sample size ( n ) = 81
Population mean
= 79
Standard deviation
= 18
(a) Describe the sampling distribution of 
For large sample using central limit theorem
the sampling distribution of
= Population mean = 79
(b) What is Upper P (
greater than 81.2 ) =
= 
= 
= 
= 1 - .8643 =
= 0.1357
(c) What is Upper P (
less than or equals 74.4 ) =
= 
= 
= .0107
(d) What is Upper P (77.6 less than
less than 83.2 ) =
= 
= 
= 
= 0.9821 - .2420
= 0.7401
By using Associative, Commutative, and Distributive Properties in performing operations on complex numbers and polynomials, you would be able to simplify correctly and simply. To combine complex numbers, you must distribute any coefficients in front of the parentheses. Then identify and<span>combine like terms by combining the real number parts and the imaginary number parts separately.</span>
