Final answer:
The point estimate for the population proportion of adult Americans aged 18 and older who believe televisions are a luxury is calculated to be approximately 0.4919, or 49.19%, based on survey data of 1537 individuals of which 756 responded affirmatively.
Step-by-step explanation:
The student is asking for a point estimate of the population proportion of adult Americans aged 18 and older who believe televisions are a luxury they could live without. To calculate this estimate, we use the data from the survey: 756 out of 1537 adult Americans indicated that televisions are a luxury they could live without. The point estimate is found by taking the number of positive responses and dividing it by the total number of responses.
Here's the calculation:
- Point Estimate = Number of adults who believe TVs are a luxury / Total number of adults surveyed
- Point Estimate = 756 / 1537
- Point Estimate = 0.4919 (to four decimal places)
Therefore, the point estimate for the population proportion is approximately 0.4919, or 49.19%.
