Final answer:
The point estimate for the proportion of all restaurant patrons who prefer chicken in their fried rice is approximately 31.7%, calculated by dividing the number of patrons who like chicken most (129) by the total number surveyed (407) and converting the result to a percentage.
Step-by-step explanation:
To obtain a point estimate for the proportion of all restaurant patrons who like chicken the most of any fried rice dish, we use the data provided from the survey of 407 restaurant patrons. Among these, 129 indicated that they preferred chicken in their fried rice dishes.
To calculate the point estimate of the proportion, we divide the number of patrons who liked chicken the most by the total number of patrons surveyed and then convert the result into a percentage:
Point estimate = (Number of patrons who prefer chicken) / (Total number of patrons surveyed)
Point estimate = 129 / 407
Now, let's convert this into a percentage:
Point estimate (as a percentage) = (129 / 407) × 100
Point estimate (as a percentage) ≈ 31.7%
Therefore, based on the survey data, we can estimate that approximately 31.7% of all restaurant patrons like chicken the most in their fried rice dishes. This figure is rounded to one decimal place as needed.
