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:
<u>Option 4:</u> -6.1 - (-3.13)
Step-by-step explanation:
Let's solve each option individually to see if -2.97 fits as the solution:
-6.1 - 3.13 = -9.23
-6.1 - (-31.3) = 25.2
-0.61 - (-3.13) = 2.52
<u>-6.1 - (-3.13) = </u><u>-2.97 </u>
As you can see, -2.97 is the answer to Option 4.
So, the decimal -2.97 is the solution to the subtraction problem in Option 4.
Sum of all interior angles on a polygon is
180( n - 2) n = number of sides in the polygon.
now, this one is is a 21-gon, thus the sum is 180( 21 - 2).
