Final answer:
The point estimate for the population proportion of left-handed musicians, based on a survey of 2,170 musicians where 346 were left-handed, is 15.94%.
Step-by-step explanation:
To find a point estimate for p, the population proportion of musicians that are left-handed, we use the formula point estimate = (number of successes) / (total number of trials). Here, the number of successes (left-handed musicians) is 346, and the total number of trials (musicians surveyed) is 2,170. So, the point estimate is calculated as follows:
point estimate = 346 / 2,170 = 0.1594
This means that the estimated proportion of left-handed musicians in the population, based on this sample, is 15.94%.
