To find the percentile of a number, we simply use the formula:
It has been given in the problem statement that there are 207 values below 88.6 and the total number of observations is 300. We simply just divide these and multiply the quotient by 100.
ANSWER: 88.6 is in the 69th percentile.
Answer:
Confidence limit = [52.8%, 75.2%]
Step-by-step explanation:
± 
where the value will be taken from the z-table for 95% confidence interval
1-0.95= 0.05/2= 0.025
0.95+0.025= 0.0975
From the z-table the value of corresponding to 0.0975 is 1.96
±

Answer:
Step-by-step explanation:
150/x=sin 15
x=150/sin 15 ≈579.56 m
To put this into an equation, we can make x the amount of two year old's there are.
x+2x+2x=45
5x=45
x=9
9 two year old's, 18 three year old's, and 18 four year old's.
