we know that
The simple interest formula is equal to
where
I is the simple interest
P is the principal ( the amount borrowed or deposited)
r is the interest rate
t is the time
in this problem we have
Substitute the values in the formula above
therefore
<u>the answer is</u>
The amount of interest earned is equal to
Answer:
WE fail to reject the Null and conclude that ; Standard deviation of test hasn't decreased.
Step-by-step explanation:
The hypothesis :
H0 : σ = 13
H1 : σ < 13
Using the Chisquare Square statistic :
χ² = (n-1)*s²/σ²
Sample size, n = 25
s² = 6.0547²
σ² = 13²
χ² = (25 - 1)*6.0547² / 13²
χ² = 879.82541016 / 169
χ² = 5.206
The degree of freedom, df = 25 - 1 = 24
The Pvalue(5.206, 24) = 0.99981
Reject H0, if Pvalue < α ;
Since Pvalue > α ; WE fail to reject the Null and conclude that ; Standard deviation of test hasn't decreased.
2.8/2 = 1.4 per liter
3.9/12 = 0.325 per liter
Bottle of juices have a higher liter is 1.4
