1.4•1.58= 2.212 is your answer because if it cost 1.58 per pound and it is 1.4 lbs your answer will be 2.212
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:

The most appropriate comparison of the spreads will be A) The median for the Wolverines 80 is more than the median for the Panthers 70
-2(1+2x)=7-x
-2(1)=-2 -2(2x)=-4x rewrite
-2-4x=7-x combine like terms add two to both sides 7+2=9; add x to both sides -4x+x=-3x rewrite -3x=9 divide -3 from both sides 9/-3=-3 rewrite
X=-3
Hope this helps have a nice day!
