A survey by the American Veterinary Medical Association found that out of 120 families surveyed, 18 owned a bird. Fifteen years
ago, a similar study found that only 5 families out of 100 surveyed had a bird. Are the validity conditions for a two-sample z-test/interval adequately met
The answer is B. $65.10 7% of $51.26 is $3.59, which adds up to $54.85 20% of $51.26 is $10.25, which, with the tax included here, adds up to $65.10. Hope this helped.
