Answer: 0.345
Step-by-step explanation:
Given : The incomes of families in Newport Harbor are normally distributed with Mean : 
and Standard deviation : 
Samples size : n=4
Let x be the random variable that represents the incomes of families in Newport Harbor.
The z-statistic :-
For x= $800,000
By using the standard normal distribution table , we have
The probability that the average income of these 4 families exceeds $800,000 :-
Hence, the probability that the average income of these 4 families exceeds $800,000 =0.345
25.40
divide by 10 for 10%: 2.54
divide it by 2: 1.27
add 2.54 and 1.27: 3.81
add the 2 numbers together: 25.40+3.81= $29.21
Your answer is $29.21
|-394| = 394 is the answer since all negative absolute values turn positive
