Question

if your null and alternative hypothesis are:
$h_0: p = 0.16$
$h_1: p < 0.16$

then the test is:
left tailed
two tailed
right tailed

Explanation:

To determine the type of hypothesis test, we analyze the alternative hypothesis ($H_1$). A left - tailed test occurs when the alternative hypothesis has a less - than ($<$) sign, as it focuses on values to the left of the null hypothesis value in the sampling distribution. Here, $H_1:p < 0.16$, so we are looking for evidence that the population proportion $p$ is less than 0.16, which corresponds to a left - tailed test. A two - tailed test would have a $
eq$ sign in $H_1$, and a right - tailed test would have a $>$ sign.

Answer:

A. left tailed
