Since the question is asking for the perimeter, you have to find the length of the sides of the rectangle.

If one of the sides has a length of 5 yards, then the side parallel to that side also has a length of 5 yards.

So you have to multiply 5 with 2

5×2=10

If the other side has a length of 3 yards, then the side parallel to that side also a length of 3 yards

So you have to multiply 3 with 2

3×2=6

Then you add the two answers

10+6=16

So you get 16 yards

Hope this helps!

Anastasy [175]

Answer:

Test statistic (t) = 0.625

Step-by-step explanation:

Step(i):-

mean of the Population(μ) = 10.4 hours

Sample mean (x⁻) = 10.7 hours

Standard deviation of the sample( S) = 1.44

The level of significance (α= 0.1

Sample size 'n' = 9

Degrees of freedom = n-1 = 9-1 =8

Step(ii):-

Test statistic

$t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }$

$t = \frac{10.7 -10.4}{\frac{1.44}{\sqrt{9} } } =0.625$
