16x11 which equals 176 so that’s the area
If two samples are selected from the same population, the two samples have exactly the same t statistics if the samples are same size and have the same variance and mean
The t-statistic is the ratio of the departure of the estimated value of a parameter from its hypothesized value to its standard error.
Variance is the expectation of the squared deviation of a random variable from its population mean or sample mean.
Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers
Hence, If two samples are selected from the same population, the two samples have exactly the same t statistics if the samples are same size and have the same variance and mean

Answer:
The shorter sides are 17 2/3 cm long
Step-by-step explanation:
Yes, you explained it right.
Let's remember that an hexagon has 6 sides, so the perimeter is the sum of the lengths of all the sides.
I assume there are 3 longer sides and 3 shorter sides. (it could be 4/2, but not 5/1 based on the use of plurals in the question).
If it was a regular hexagon the perimeter would be 6x a side length.
But it's not a regular one, however we know the link between the various lengths. So, let's input what we know, taking x as the length of a short side:
162 = 3x + 3 (2x + 1) = 3x + 6x + 3
159 = 9x
x = 17 6/9 so 17 2/3 cm
