Answer:
Kindly check explanation
Step-by-step explanation:
The hypothesis :
H0 : μ1 = μ2
H1 : μ1 > μ2
Given :
x1 = 21.1 ; n1 = 53 ; s1 = 1.1
x2 = 20.7 ; n2 = 46 ; s2 = 1.2
The test statistic :
(x1 - x2) / √[(s1²/n1 + s2²/n2)]
(21.1 - 20.7) / √[(1.1²/53 + 1.2²/46)]
0.4 / 0.2326682
Test statistic = 1.719
The degree of freedom using the conservative method :
Comparing :
Degree of freedom = n - 1
Degree of freedom 1 = 53 - 1 = 52
Degree of freedom 2 = 46 - 1 = 45
Smaller degree of freedom is chosen ;
The Pvalue from Test statistic, using df = 45
Pvalue = 0.0462
Pvalue < α ; Hence, there is significant evidence to conclude that average age of Gorka student is higher than Yaphoa.

Answer:
500+3+ .200+.008
Step-by-step explanation:
You add 500 and 3 then after you get your number add .200 lastly add .008.
when expanding numbers you need to know what place value it's in so that you k ow where to put the zeros.
Value of x is
and y is 
Solution set is (
,
)
Step-by-step explanation:
We need to solve the system of equations given.

Solving
Let:

Multiply eq(1) by 3 and eq(2) by 2 and add both

Putting value of y in equation 1

So, value of x is
and y is 
Solution set is (
,
)
