Answer:

Set of hypothesis.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 20.5 oz

Sample mean, $\bar{x}$ = 20.4 oz

Sample size, n = 50

Population standard deviation, σ = 2.25 oz

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 20.5\text{ oz}\\H_A: \mu < 20.5\text{ oz}$

We use One-tailed z test(left tailed) to perform this hypothesis.

Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$z_{stat} = \displaystyle\frac{20.4 - 20.5}{\frac{2.25}{\sqrt{50}} } = -0.3142$

Based on the significance level, we can make our decision and complete the hypothesis testing.

We may accept the null hypothesis or fail to accept depending on different significance level.

C is also not in the range though. This problem has more than one right answer. C could be a correct answer as well.
