Question

Healthy Living From a large group of people who signed a card saying they intended to quit smoking, $1000$ people were selected at random. It turned out that $210(21\%)$ of these individuals had not smoked over the past $6$ months.

Short answer

All people who signed a card promising to quit smoking were included in the population.

• $1000$participants were chosen at random after signing a card stating their intention to quit smoking.
• Statistic: p=sample proportion of those who haven't smoked in the previous $6$months$=21\%=0.21$.
• $p$=the proportion of people in the population who haven't smoked in the last six months.

Step-by-step solution

Given information

We need to find out the population, parameter, sample, and statistics.

Explanation

The $21$percent is based on the $1000$persons in the sample, therefore it represents the sample proportion of people who haven't smoked in the previous six months, implying that $21$percent is a statistic.

The population proportion of people who haven't smoked in the last six months is the comparable parameter.

Statistic: $p=$sample proportion of those who haven't smoked in the previous $6$months$=21\%=0.21$

$p=$the proportion of people in the population who haven't smoked in the last six months.
