In the "hunting cats' example, the sample proportion of the original n = 140 sample was 0.35. We have found that the standard error is SE=0.04 and the 95% confidence interval for the population proportion of US household cats that hunt outdoors is
(0.271, 0.429)
Is it plausible that the proportion of household cats in the US hunting outdoors is 0.5?
Is it plausible that the proportion of household cats in the US hunting outdoors is 0.4 ?
O A. Both are plausible values.
OB. None of them are plausible values.
OC. P=0.5 is not in the confidence interval, so 0.5 is not a plausible value for the population proportion.
p = 0.4 is in the confidence interval, so 0.4 is a plausible value
O D. None of the other answer choices
