Question
There is a species of crickets with long wings and short wings. You count the number of individuals with long wings and the number of individuals with short wings. You calculate a X^2 test statistic from these data (X2=6.8). Is there a statistically significant difference between the number of long winged and short winged crickets? What are the degrees of freedom? What is the p value? We report statistical data using the following format: There is a statistically significant difference between and (X^2= df= pExplanation / Answer
2. If the chi square is large it shows that the difference between expected and observed ratios is large.
The organism being tested is a monohybrid with long wings and short wings. A
There are two phenotypes, so there is one degree of freedom.
X2 = 6.8
The probability is between 0.01 and 0.001
The probability is less than 0.10, so the deviation is significant and chance alone is not the cause.So, the hypothesis is correct.
