In a poll, 312 of 1040 randomly selected adults aged 18 or older stated that they believe there is too little spending on national defense.

Obtain a point estimate for the proportion of adults aged 18 or older who feel there is too little spending on national defense.

  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 : n=1040

Out of them , the number of persons stated that they believe there is too little spending on national defense: x= 18

Let p 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 , the sample proportion is the best estimate of the population proportion.

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.
