The value of test statistic is 5.45
Data;
- n1 = 25
- n2 = 30
- x1 = 6.2
- x2 = 3.8
- s1 = 2
- s2 = 1
<h3>Test Statistic</h3>

19.625cm squared because you have to divide the diameter by 2 to get the radius.
Area of circle = pi times radius times radius
= 3.14 times 2.5 times 2.5
= 19.625cm squared
Step-by-step explanation:
1.623/100
=1.623×10^-2
or
=0.01623

Compute the gradient of
.

Set this equal to the zero vector and solve for the critical points.








The last case has no real solution, so we can ignore it.
Now,


so we have two critical points (0, 0) and (2, 2).
Compute the Hessian matrix (i.e. Jacobian of the gradient).

Check the sign of the determinant of the Hessian at each of the critical points.

which indicates a saddle point at (0, 0);

We also have
, which together indicate a local minimum at (2, 2).
