Christine is investigating the proportion of adult employees from her region who walk or bike to work on a regular basis. Christine selects 624 adult employees at random from across the region and found that 92 either walk or bike to work on a regular basis. What is an estimate of the population proportion for adult employees from Christine's region who either walk or bike to work on a regular basis? Round to three decimal places.
Completely lost on this question any help would be appreciated.
92/624 = 0.1538 = 15.38%
To estimate the population proportion of adult employees who either walk or bike to work on a regular basis, we need to use the sample information provided by Christine.
First, we can calculate the sample proportion, which represents the proportion of employees in the sample who either walk or bike to work on a regular basis. This can be obtained by dividing the number of employees who walk or bike (92) by the total number of employees in the sample (624).
Sample proportion = 92/624
Next, we can use this sample proportion to estimate the population proportion. Since Christine selected her sample randomly from across the region, we can assume that the sample is representative of the entire population. Therefore, we can use the sample proportion as an estimate of the population proportion.
Estimated population proportion = Sample proportion = 92/624
Now let's calculate the value:
Estimated population proportion = 92/624
Estimated population proportion ≈ 0.147
Rounding to three decimal places, the estimated population proportion for adult employees who either walk or bike to work on a regular basis is approximately 0.147.
