Answer: (0.1658, 0.2742)
Step-by-step explanation:
Formula to find the confidence interval for population proportion is given by :-

, where n= sample size
z*= Critical value
= sample proportion.
As per given , we have
Significance level : 
According to z-table, Critical value for 99% confidence interval : z*=2.576
Let p be the proportion of people in the country that have red hair.
n= 388

Now, required confidence interval for proportion of people in the country that have red hair will be :-




The 99% confidence interval for the proportion of people in the country that have red hair= (0.1658, 0.2742)
