A survey includes a series of questions about automobile automation technology. The 1,010 interviews completed in the survey showed that 219 respondents feel manufacturers should focus on developing self-driving vehicles. In addition, 802 respondents want current vehicle safety systems (such as automatic emergency braking and lane keeping assistance) to work better, and 599 respondents want these systems in the next vehicle they purchase. (a) Develop a point estimate of the proportion of respondents who feel manufacturers should focus on developing self- driving vehicles. (Round your answer to four decimal places.) (b) Develop a point estimate of the proportion of respondents who want current vehicle safety systems (such as automatic emergency braking and lane keeping assistance) to work better. (Round your answer to four decimal places.) (c) Develop a point estimate of the proportion of respondents who want current vehicle safety systems (such as automatic emergency braking and lane keeping assistance) in the next vehicle they purchase. (Round your answer to four decimal places.) (

**(a)**  
The point estimate is given by  
$$
\hat{p} = \frac{\text{number of respondents who favor self-driving vehicles}}{\text{total number of respondents}}.
$$  
Substitute the given values:  
$$
\hat{p} = \frac{219}{1010} \approx 0.2168.
$$

**(b)**  
The point estimate is given by  
$$
\hat{p} = \frac{\text{number of respondents who want current safety systems to work better}}{\text{total number of respondents}}.
$$  
Substitute the values:  
$$
\hat{p} = \frac{802}{1010} \approx 0.7931.
$$

**(c)**  
The point estimate is given by  
$$
\hat{p} = \frac{\text{number of respondents who want these systems in the next vehicle}}{\text{total number of respondents}}.
$$  
Substitute the values:  
$$
\hat{p} = \frac{599}{1010} \approx 0.5921.
$$
**(a)** Proportion of respondents favoring self-driving vehicles: 0.2168 **(b)** Proportion of respondents wanting current safety systems to work better: 0.7931 **(c)** Proportion of respondents wanting current safety systems in the next vehicle: 0.5921
