b. 0.051
c. 
Step-by-step explanation:
Let p be the population proportion of parents spend too little time with their children because of work commitments

n= 369

Since the sample proportion is the best estimate for the population proportion.
So , the point estimate of the proportion of the population of working parents who feel they spend too little time with their children because of work commitments = 0.542
z-value for 95% confidence interval : 
Margin of error : 

The margin of error = 0.051
Confidence interval : 

95% confidence interval estimate of the population proportion of working parents who feel they spend too little time with their children because of work commitments : 
Answer:
