Variables: x, y, z (we should multiply them and put them together )
Then coeffitions, we should multiply them
Now put coeffitions before variables:
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 :
