Explanation
## Step 1: Understand the sampling method used. In this case, the first house was selected randomly, and then every eighth house was selected. This is a systematic sampling method, not a simple random sample. In a simple random sample, every member of the population has an equal chance of being selected, which is not the case here.## Step 2: Identify the type of data for "Number of times per week". This is quantitative data because it represents a countable number of times.## Step 3: Identify the type of data for "Duration (amount of time)". This is also quantitative data because it represents a measurable amount of time.## Step 4: Identify the type of data for "The colors of the houses around the park". This is qualitative or categorical data because it represents a characteristic or quality (color) rather than a count or measure.## Step 5: Identify the population for this study. The population for this study is all the residents of the houses in the neighborhood around the park.
