Given that, the green skin (G) is dominant to yellow (Y). Cross between the green creature and yellow creature will have the offspring with the following genotypes.
Gg* yy = Gy, Gy, gy, gy (Means, 1:1 ratio of green and yellow offspring, but the observed values are in 3:2 (12:8) ratio).
Now, the Chi-square value can be calculated as follows. (O= Observed, E= Expected)

Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The population proportion is
The mean of the sampling distribution is
The sample size is n = 600
Generally the standard deviation is mathematically represented as
=>
=>
Generally the probability that the proportion of airborne viruses in a sample of 600 viruses would differ from the population proportion by greater than 3% is mathematically represented as
=>
Now add p to both side of the inequality
=>
=>
Now converting the probabilities to their respective standardized score
=>
=>
=>
From the z-table
and
So
=>
