for this case we must write a proportion that shows the earnings obtained from Mrs. Miller for the sale of the house.
By making a rule of three we have:
179000 ------------> 100%
x -----------------------> 6%
Where "x" represents the gains obtained.
So:
Writing the proportion:
The earns were:
ANswer:
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 :
Answer:
Step-by-step explanation:
the error was in not take the root of the number correctly
the student assumes that the root of 144 was equal to 72
