A political action committee wanted to estimate the proportion of county residents who support a change to the county leash law.

They took a random sample of 600 county residents and found that the proportion who wanted to change the law was 30% with a margin of error of 4% (based on 95% confidence). This implies:
Select one:

a. We believe that the true proportion of county residents who want the law changed is between 26% and 34%
b. We can not conclude anything about the population parameter since this is only a sample.
c. If we took another sample of 600 residents the sample proportion would definitely be between 26% and 34%
d. There is a 95% chance that the true parameter is 30%
e. If we take many other samples from this population 95% of them will have a sample proportion that is between 26% and 34%.

Answer:

a. We believe that the true proportion of county residents who want the law changed is between 26% and 34%

Step-by-step explanation:

The sample point estimate, at a 95% percent confidence level, gives the political action committee an estimate of the true proportion of residents who support a change to the county leash law within a margin of error.

If the point estimate was 30% with a margin of error of 4%, there's a 95% chance that the true proportion is between 26% and 34%.

Therefore, the correct answer is: a. We believe that the true proportion of county residents who want the law changed is between 26% and 34%

An arc on a circle measures 250°. Within which range is the radian measure of the central angle? 0 to StartFraction pi Over 2 En
Alex Ar [27]

Answer:

The central angle is within the range π to 3π/2

Step-by-step explanation:

To convert from degrees to radians, we multiply the angle in degrees by 180/π.

To convert from radians to degree, we multiply the angle in radians by 180°/π.

π/2 = π/2 X 180°/π= 90°

π rad = π X 180°/π= 180°

3π/2 = 3π/2 X 180°/π= 270°

2π = 2π X 180°/π= 360°

Therefore the angle 250 which is between 180 and 270 is within the range :

π to 3π/2
