Answer:
x = 10
Step-by-step explanation:
Use Pythagorean theorem to find the value of x
Focus only on one half of the triangle
if we slice the triangle in half, we get a right angle triangle
the base will now be 12/2 = 6
Pythagorean theorem says that
plug 6 as a and 8 as b.
this should give you 100
now take the square root to find c (which equals x)
Ta-da!

Test statistic:
In which X is the sample mean, is the expected value,
is the standard deviation and n is the size of the sample.
A company advertises that its cans of caviar each contain 100 g of their product.

They calculate a sample mean weight of 99 g and a sample standard deviation of 0.9 g. Sample of 8 cans.
This means that
So the test statistic will be given by:
The value of the test statistic is -3.14.
