Answer: A point estimate for the proportion of adults aged 18 or older who feel there is too little spending on national defense is 0.3.
Step-by-step explanation:
Given : In a poll , the sample size of adults aged 18 or older : <em>n</em>=1040
Out of them , the number of persons stated that they believe there is too little spending on national defense: <em>x</em>= 18
Let <em>p</em> be the proportion of adults aged 18 or older who feel there is too little spending on national defense.
Now , as per sample , the sample proportion of adults aged 18 or older who feel there is too little spending on national defense would be :

Since , <em>the sample proportion is the best estimate of the population proportion.</em>
Therefore, a point estimate for the proportion of adults aged 18 or older who feel there is too little spending on national defense is 0.3.
1. cos (angle) = adjacent leg / hypotenuse
cos(50) = 10/X
x = 10/cos(50)
x = 15.6 feet
2.
tan(angle) = Opposite leg / adjacent leg
tan(5.5) = 600/x
x = 600/tan(5.5)
x = 6,231.2 feet.
