Since 
null hypothesis on this data is not rejected.
<h3>Null and Alternative Hypothesis</h3>
Data;
- sample mean x1 = 240993
- population standard deviation σ1 = 25875
- sample size n1 = 35
- sample mean x2 = 249237
- population standard mean σ2 = 27110
- sample size n2 = 35
- significance level α = 0.10
H_o = μ1 = μ2
H_o = μ1 ≠ μ2
This is a two-tailed test and population standard deviation will be used.
<h3>Test Statistic</h3>
The z-stat is
The significance level is α = 0.1 and the critical value for a two-tailed test is
Since , we can assume that the null hypothesis is not rejected.

Answer:
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above
He can split his pop into in whole mLs any n glasses such that n is a divisor of 30, namely any n in {1,2,3,5,6,10,15,30}. The fraction in each glass is then 1/n.
First find the slope.
-6--2=-4
-2--1=-1
The slope is -4/-1 or 4.
Now plug in one point and the slope into point slope
y-y1=m(x-x1)
y+2=4(x+1)
