the blood pressure values taken from the female patients in the sample.
a continuous variable.
a nominal variable.

Explanation:

To solve these questions, we analyze each part based on the context of a study about blood pressure (likely from female patients, given the options):

1. The population of interest is:

The population is the entire group we want to draw conclusions about. Since the study involves estimating the average systolic blood pressure (implied to be for female patients, as seen in sample - related options), the population of interest is all females (option 6).

2. The cases in this study are:

"Cases" in a study refer to the individual units being studied. Here, the units are the female patients included in the table (option 4), as we are analyzing their blood pressure.

3. The variable (blood pressure) is:

Blood pressure is a numerical measurement that can take any value within a range (e.g., 110, 120, 130, etc., and even decimal values in precise measurements). Thus, it is a continuous variable (option c, where option c corresponds to "a continuous variable" from the blue - boxed options).

4. The sample is:

The sample is a subset of the population. Since the population is all females, the sample is the blood pressure values taken from the female patients in the sample (option a, where option a corresponds to "the blood pressure values taken from the female patients in the sample" from the blue - boxed options).

5. The maximum sample size possible is:

This depends on the number of female patients (cases) in the study. If we assume the table has, say, \( n \) female patients, the maximum sample size is the number of female patients (cases) in the study (since the sample is from these cases). If we take the options' context (and typical study setups), and assuming the cases are the female patients in the table, the maximum sample size is the number of female patients (so if there are, e.g., 5 female patients, the sample size is 5; but from the options' logic, it's the number of female patients in the study, so we'd choose the option corresponding to the number of cases, but since the exact number isn't fully visible, from the study's context, it's the number of female patients included (the cases), so the maximum sample size is the number of female patients in the study (the cases we identified earlier).

Final Answers (for each sub - question, in order):

1. The population of interest is: 6. all females
2. The cases in this study are: 4. female patients included in the table
3. The variable (blood pressure) is: c. a continuous variable
4. The sample is: a. the blood pressure values taken from the female patients in the sample
5. (Depends on the number of cases; if we assume the cases are the female patients in the table, the maximum sample size is the number of female patients in the table)
