A study finds that 167 out of 298 seals sampled from an ecosystem are earless. Which of the following gives a 90% confidence interval for the proportion of seals that are earless?Group of answer choices[0.52, 0.60][0.51, 0.61][0.50, 0.62][0.49, 0.63]We don't need a confidence interval, because the proportion of earless seals is clearly just 167/298.
