Answer: a. 0.542
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
As per given , we have
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 :
Ok, so dy/dx=0 at the point (0,3) that is where x=0 and y=3.
Now, f'(x)=0 when x=0.
Therefore:
Now:
But when x=0, y=3, therefore:
Now, f'(x)=0 when x=0.
Therefore:
Now:
But when x=0, y=3, therefore:
