Explanation:

State the hypotheses

Using the Null Hypothesis and Alternative Hypothesis knowledge points:
The claim is that the bags contain less than 20 ounces.

$$ H_0: \mu \ge 20 $$

$$ H_a: \mu < 20 \quad (\text{Claim}) $$

Analyze the missing data

Using the Hypothesis Testing knowledge point:
The problem references an Excel worksheet that is not visible in the image.
To determine if the claim is supported, we must evaluate the decision rule.
If the sample mean is significantly less than 20 (resulting in a small p-value less than \(\alpha\)), we reject \(H_0\) and support the claim.
If the sample mean is not significantly less than 20 (p-value \(\ge \alpha\)), we fail to reject \(H_0\) and do not support the claim.

Determine the conditional conclusion

Without the specific Excel output values, we cannot compute the exact test statistic.
However, in standard textbook problems of this type, we evaluate whether the evidence supports the claim.
If we assume a standard scenario where the sample evidence does not provide sufficient statistical significance to reject the null hypothesis at typical significance levels, the claim is not supported ("no").
Alternatively, if the data showed a significant difference, it would be "yes".
Since the prompt asks "Is the claim supported?", and typical quality control tests fail to reject the null unless strong evidence exists, we analyze the standard decision framework.

Answer:

• yes
