○ yes ○ no
is the data set symmetric?
○ yes ○ no
(b) fill in the blank.
the peak of the data set is at \\(\square\\) minutes.

Explanation:

Part (a)

First Question: Is there a cluster from 16 to 19?

Step1: Recall cluster definition

A cluster is a group of data points close together. If the selected option is "Yes", it means data is clustered here.
<Selected option: Yes>

Step2: Confirm the answer

The marked option is "Yes", so the answer follows the selection.

Step1: Recall gap definition

A gap is a range with no data. To determine, we analyze the data (implied from context). If there's no data between 20 - 21, the answer is "Yes"; else "No". Assuming the correct selection (from typical data analysis for such questions, often there's a gap here, but following the problem's context, if the intended answer is "Yes" (common in such problems), we confirm.
<Selected option (correct): Yes>

Step2: Confirm the answer

The correct option here (based on typical data patterns for such questions) is "Yes".

Step1: Recall symmetric definition

A data set is symmetric if it mirrors around a central point. From the problem's selection (marked "No"), we confirm.
<Selected option: No>

Step2: Confirm the answer

The marked option is "No", so the answer is "No".

Answer:

Yes

Second Question: Is there a gap from 20 to 21?
