Final answer:
The point estimate for the population proportion of left-handed golfers is calculated by finding the sample proportion (p'), which in this case is approximately 0.172, or 17.2%.
Step-by-step explanation:
To find a point estimate for p, the population proportion of golfers that are left-handed, we will use the formula for calculating a sample proportion:
p' = x/n, where x represents the number of successes and n represents the sample size. The variable p' is the sample proportion and serves as the point [estimate for the true population proportion](8.3 A Population Proportion).
In this survey of 2140 golfers, 1772 are right-handed. Hence, the number of left-handed golfers (our 'success' in this context) would be:
2140 total golfers - 1772 right-handed golfers = 368 left-handed golfers
Now we can calculate the sample proportion of left-handed golfers:
p' = 368/2140 ≈ 0.172
Therefore, the point estimate for p, the population proportion of left-handed golfers, is approximately 0.172, or 17.2%.
