Answer #1

Given that, n = 70 and x = 42

=> sample proportion = 42/70 = 0.6

A 95% confidence level has significance level of 0.05 and critical value is,

The 95% confidence interval for the population proportion is,

Therefore, a 95% confidence interval for the population proportion of male dogs who come to shelter as strays is (0.4852, 0.7148).

A 2009 study to investigate the dominant paws in cats was described in Animal Behaviour (Volume 78, Issue 2). The researchers used a random sample of 42 domestic cats. In this study, each cat was shown a treat (5 grams of tuna), and while the cat watched, the food was placed inside a jar. The opening of the jar was small enough that the cat could not stick its head inside to remove the treat. The researcher recorded the paw...
