Answer:
This relationship is a function
Step-by-step explanation:
By definition a relation is defined as a function if and only if for each input value x there is only one output value y.
In this case we observe the following ordered pairs
(0.2), (1.2), (2.2) (3.2)
We see that each value x has only a value of y.
Therefore this relationship is a function
is it compounded yearly? if so,
CI = p(1+ r/100)^n
= 750 (1+ 1.75/100)^5
= $818.00 (nearest 10 cents)
Answer:
A)
Note that
Lower Bound = X - z(alpha/2) * s / sqrt(n)
Upper Bound = X + z(alpha/2) * s / sqrt(n)
where
alpha/2 = (1 - confidence level)/2 = 0.025
X = sample mean = 1723.4
z(alpha/2) = critical z for the confidence interval = 1.959963985
s = sample standard deviation = 89.55083319
n = sample size = 30
Thus,
Lower bound = 1691.355235
Upper bound = 1755.444765
Thus, the confidence interval is
( 1691.355235 , 1755.444765 ) [ANSWER]

b)
We assumed taht the distirbution of these observations is approximately normally distributed.

c)
Yes, because the values are not far away from each other.
Answer:
The maximum amount of sand in ounces that the company allows for each bottle is 25.5 ounces.
Step-by-step explanation:
The amount of sand that the company Sandy stores allows in each small bottle is determined by the amount of sand required for the bottle size plus the error in the amount of sand for the bottle size.
Now since each small bottle contains 25 ounces of sand and the error in the amount of sand contained in the bottle is 0.5 ounces, the amount of sand contained in the bottle = required amount ± error.
For the minimum amount, we subtract the error and for the maximum amount, we add the error.
Since the maximum amount is required, we have,
Maximum amount = required amount + error
required amount = 25 ounces and error = 0.5 ounces. So, Maximum amount = 25 ounces + 0.5 ounces = 25.5 ounces.
So, the maximum amount of sand in ounces that the company allows for each bottle is 25.5 ounces.
2×-2=-4
-4 × -2 = 8
8 × -2 =-16
-16×-2 =32
32 ×-2 = -64.
therefore the answer is -2.
