Answer:
x = (y + 26)/5
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
y + 6 = 5(x - 4)
Step 2: Distribute
y + 6 = 5x - 20
Step 3: Isolate <em>x</em>
y + 26 = 5x
Step 4: Isolate variable <em>x</em>
(y + 26)/5 = x
Step 5: Rewrite
x = (y + 26)/5

Answer with explanation:</h2>
When the sample size is small (< 30) and the population standard deviation is unknown , then we use t-test.
The confidence interval for population mean will be :
(1)
, where
= sample mean
t* = Critical value (based on degree of freedom and significance level).
s= sample standard deviation
n= sample size.
As per given we have
n= 9
Degree of freedom = n-1 = 8

s= 0.75
Significance level =
Using students' t distribution table ,
Critical value : 
We assume that the population is approximately normal.
Then, a 80% confidence interval for the mean waste recycled per person per day for the population of Florida will be :
(Substitute the values in (1))



Hence, the 80% confidence interval for the mean waste recycled per person per day for the population of Florida. = (2.047, 2.753)
