Answer:
$3.96.
Step-by-step explanation:
3 cost $0.99, so 12 packs would cost 12/3 = 4 times as much.
0.99 * 4 = 3.96.
12 packs would cost $3.96.
Hope this helps!
The correlation coefficient for the data in the table is A. –0.993
<h3>Calculations and Parameters:</h3>
Using this formula: 
We would use x and y to represent the unknowns.
n = 4
We have,
- ∑x = 42,
- ∑y = 44.37 ,
- ∑xy = 461.3
- ∑x^2 = 446,
- ∑y^2 = 494
Putting these values in the formula would bring the answer as. A. –0.993

Answer: t _(α/2) = 2.060
Step-by-step explanation:
Given that;
sample size n = 26
confidence interval = 95%
level of significance α = ( 1 - 95/100 ) = 0.05
but from the question the salaries (26) are use to estimate the mean of the population so, its a two tail test
therefore our level if significance α will be divided by 2 = 0.05/2 = 0.025
now our degree of freedom df = 26 - 1 = 25
FROM standard t-table value
the critical value of t for the level of significance 0.025
and 25 degree of freedom is 2.060
therefore, t _(α/2) = 2.060
