Given that a survey of 500 likely voters showed that 385 felt that the economy was the most important national issue.
Sample size n = 500
favor who feel the ecomomy is the most important national issue x= 385
Sample proportion =
Sample proportion would be the point estimate for population proportion of voters who feel the ecomomy is the most important national issue.
Hence the point estimate (p-hat0 for p, the population proportion of voters who feel the ecomomy is the most important national issue
is 0.77

Answer:
The volume of tennis ball = 38.808 .
Volume of golf ball = 33.523 .
Step-by-step explanation:
Given: The radius of the tennis ball is 2.1cm and the radius of thr golf ball is 2.0cm. the formula is V=4πr(to the 3rd power) /3 .
To find: Volume of tennis ball and golf ball .
Formula used: Volume = .
pi(π) = .
Explanation : We are given that
Radius of the tennis ball = 2.1 cm
radius of the golf ball =2.0 cm.
We need to find the volume of each ball
So , plugging the given values of radius in above formula
Volume of the tennis =
On simplification we get, volume of tennis ball = 38.808
Volume of the golf ball=
On simplification we get, volume of golf ball = 33.523
Therefore , The volume of tennis ball = 38.808 .
Volume of golf ball = 33.523 .
