Answer: 0.137.
Step-by-step explanation:
Let p be the population proportion of musicians that are left-handed.
Given: Sample size : n= 2690 [subset of population]
Number of musicians that are left-handed: x= 368
Then the sample proportion: [tex]\hat{p}=\dfrac{368}{2690}\approx0.137[/tex]
Since sample proportion is the best point estimate of the population proportion.
Hence, a point estimate for p, the population proportion of musicians that are left-handed is 0.137.
