Answer:

For this case we can conclude that with 98% of confidence the true proportion of Drosophila in a population would be between 0.34 and 0.38.
But that doesn't means that we have 98% of PROBABILITY that the true proportion would be between 0.34 and 0.38, because we are constructing a confidence interval with sample data and we can't analyze this using probability.
Then the best answer is:
2. False
Step-by-step explanation:
For this case we have a confidence interval for the proportion of Drosophila in a population with mutation Adh-F to be given by:

Answer:
12.7, because the absolute value gets rid of the negative integer, and shows it true value which is positive 12.7.

I'm not 100% sure, but I'm pretty sure it's 1/12, 1/12, 1/12, 1/12
Answer:20
Step-by-step explanation:
3.1 *4.2=13.02 12.4*21=260.4 260.4/13.02=20
