Question

you are conducting a study to see if the probability of catching the flu this year is significantly different from 0.74. if your null and alternative hypothesis are: $h_0: p = 0.74$ $h_1: p
eq 0.74$ then the test is: two tailed left tailed right tailed

Explanation:

In hypothesis - testing, if the alternative hypothesis $H_1:p
eq p_0$ (where $p_0$ is a specified value), it means we are looking for a difference in either direction. A two - tailed test checks for differences in both the lower and upper tails of the distribution. A left - tailed test has $H_1:p < p_0$ and a right - tailed test has $H_1:p>p_0$. Since our $H_1:p
eq0.74$, we are interested in deviations from 0.74 in both directions.

Answer:

A. two tailed
