Question

The null and alternative hypotheses are given. Determine whether the hypothesis test is​ left-tailed, right-tailed, or​ two-tailed. What parameter is being​ tested? Upper H 0H0​: p equals 0.2p=0.2 Upper H 1H1​: p less than 0.2

Answer 1

Answer:  The parametric is being tested here is "p" (population proportion).

The hypothesis test is​ left-tailed.

Step-by-step explanation:

Given : The null and alternative hypotheses are

$H_0:\ p=0.2\\\\H_1:\ p$

The parametric is being tested here is "p", where p stands for population proportion.

Also, the type of test depends on the alternative hypotheses.

Since the alternative hypotheses is left-tailed, so the hypothesis test is​ left-tailed.
