Answer:
Mean = 94
Standard deviation = 1.12
The sampling distribution of the sample mean is going to be normally distributed, beause the size of the samples are 80, which is larger than 30.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean
and standard deviation, which is also called standard error 
In this problem, we have that:

By the Central Limit Theorem
The sampling distribution of the sample mean is going to be normally distributed, beause the size of the samples are 80, which is larger than 30.
Mean = 94
Standard deviation:

Y= 150 ( 0.88) thats the decoy rate

-6.2= b
b= -12
First, we need to figure out 10% of fifteen.
So, we multiple 15 by 10% (or 0.1 in simpler terms).
That gives us 1.5, which is our mark-up price.
So, finally we add the markup price to the original price to obtain the selling price.
1.5 + 15 = 16.5
The owner charges $16.50 for 1kg of sugar!
<em>764 in. </em>
<u>Here's why: </u>
There are 12 inches in a foot.
12*63=756
<em>Don't forget to add the extra 8 inches!</em>
756+8=764
