Answer:

Option d is correct answer.

Step-by-step explanation:

Given in the picture is a circle with a sector quadrant circle.

WE have the formula for the sector of a circle

If angle of the sector is x

then we have

area of the sector = $\frac{x}{360} (\pi r^2)$

Here x=central angle = 90 and r = radius = 8

Substitute to get

$\frac{90}{360} (\pi )(8^{2} )\\=16\pi$

Eight phenotypes were present.

Df is provided also by a number of phenotypes -1 The degree of freedom

$\to df = 8-1= 7$

For p-value 0,9, Chi-square is 2.83;

The p-value of 0.75 is 4.5. Chi-square

Chi-sqaure value is observed at 2.965.

That means 0.90>p-value>0.75.
