Answer:
One-sample Z-test
Step-by-step explanation:
As the sample size is greater than 30, assuming the data is a simple random sample, and that the data has a normal distribution, the sociologist should conduct a one-sample z-test to calculate the p-value.

If you would like to divide 2/3 by 1/2, you can do this using the following step:
2/3 / 1/2 = 2/3 * 2/1 = 4/3 = 1 1/3
The correct result would be 1 1/3.
So length is 3.9 cm more than 3 times the width
perimeter is 32.6 cm
l = 3w + 3.9
P = l + l + w + w
32.6 = 3w + 3.9 + 3w+ 3.9 + w + w
combine like terms
32.6 = 7.8 + 8w
subtract 7.8 from both sides
24.8 = 8w
divide both sides by 8 to isolate w
3.1 = w
so we solved that the width is 3.1 cm
to find the length
l = 3.9 + (3*3.1)
l = 3.9 + 9.3
l = 13.2
The dimensions:
Length is 13.2 cm
Width is 3.1 cm
Hope this helps :)
