(7x + 2 + 8x^4) – (2x – 5 – 8x^4) + (3x + 5x^4)
= 7x + 2 + 8x^4 – 2x + 5 + 8x^4 + 3x + 5x^4
= 8x + 7 + 21x^4
= 21x^4 + 8x + 7
based on the given area for the six habitats, Dullinger and his colleagues can find the p-value to be 0.0018.
<h3>how can the p-value be found?</h3>
a chi-squared test is the best test for to find the p-value and when the data given is put through a chi-square model, the observed values are:
= 7, 9, 2, 11, 2, 0
the expected values should be:
= 1/6, 1/6, 1/6, 1/6, 1/6, 1/6
the p-value will be 0.001819
df = 5
