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

Answer:
G
Step-by-step explanation:
The number of total bottles sold on that day is 40
11 + 7 + 18 + 4 = 40
On Tuesday, theoretically, this is what will be sold:
22 bottles of apple juice
14 bottles of cranberry juice
36 bottles of orange juice
8 bottles of pineapple juice
We need to find out what doesn't fit the data.
F: 14 - 8 = 6, not correct answer
G: the number of cranberry juice will be 6 times the number of pineapple juice sold? It's not even twice the amount!
H: 36 + 14 = 50, not correct answer
J: 22 - 8 = 14, not correct.
From this, G is the correct answer as it is not even close to matching the data.
