Q1:
150 pages is the answer
2 hours= 60+60minutes
So 120/40 =3
Answer= 50×3= 150.
Q2:
Using Work=men×days we get
Work=20×20
Work=400
Now, work is same and number of days are to be calculated
400=25×days
days= 16
400 = 25 x 16
so it will take 16 days

1/5x = 2/5
x = 2/5 * 5/1 (5/1 is the inverse of 1/5)
x = 2
Answer:
C.I = 0.108 ± 0.022
Step-by-step explanation:
In this case, we are given a symmetric confidence interval, and the sample proportion p', is derived by finding the average of the two values.
Therefore, the sample proportion will be:


= 0.108
p' = 0.108
To find the margin of error, we have:
M.E = ½ * length of confidence interval
Where length of confidence interval = 0.130 - 0.086
= 0.044
Therefore,

Margin of error = 0.022
The confidence interval is expressed as:
p' ± M.E
= 0.108 ± 0.022
