He goodness of fit is measured by χ2. This statistic measures the amounts by which the observed values differ from their respect
Murrr4er [49]

Answer:

Step-by-step explanation:

Hello!

Table is attached.

1) Purple stem/short petals.

(o-e)= 220-225= -5

(o-e)²= (-5)²= 25

(o-e)²/e= 25/225= 1/9

2) Green stem/short petals

(o-e)= 210-225= -15

(o-e)²= (-15)²= 225

(o-e)²/e= 225/225= 1

3) Purple stem/ long petals

(o-e)= 231-225= 6

(o-e)²= (6)²= 36

(o-e)²/e= 36/225= 4/25

4) Green stem/ long petals

(o-e)= 239-225= 14

(o-e)²= (14)²= 196

(o-e)²/e= 196/225 (≅ 0.871)

To reach the statistic value you have to add the four values obtained in the last row:

X²= 1/9+1+4/25+196/225= 482/225≅ 2.142

I hope you have a SUPER day!
