Step-by-step explanation:
There are 6 different outcomes when rolling a fair dice.
You can roll a:
1
2

There is one outcome we want. Probability=number of desirable outcomes/total number of options.
1= number of desired outcomes
6-=total number of outcomes
1/6
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:
5.1 pints
Step-by-step explanation:
Theres 2 ways
First way:
We can do 2/5 of 8.5 which is 3.4. Then, we can subtract 3.4 from 8.5 and get 5.1 pints.
Second way:
We can simply do 3/5 of 8.5 because the remaining 3/5 of the paint is blue. 3/5 of 8.5 is 5.1 pints
Hope this helped! I would appreciate a Brainliest if this helped you!
Answer:
b = -3
Step-by-step explanation:
-13 = 2b - b - 10
Add 10 to both sides of the equation
-3 = 2b - b
Subtract 2b - b
-3 = b
b = -3
