Answer:
we can conclude at 95% of confidence that the true proportion of interest for this case is between 0.287 and 0.613
Step-by-step explanation:
The estimated proportion of interest is 
We need to find a critical value for the confidence interval using the normla standard distributon. For this case we have 95% of confidence, then the significance level would be given by 
and 
.
And the critical value is:
The confidence interval for the true population proportion is interest is given by this formula:
Replacing the values provided we got:
And we can conclude at 95% of confidence that the true proportion of interest for this case is between 0.287 and 0.613
Answer:
True

Answer:
Distance of the trail from the start to the end is 
miles
Step-by-step explanation:
Distance from the start of a trail to the bird lookout point=
miles
Distance from the bird lookout point to the end of the trail =
miles
We want to find the difference of the trail from the start to the end, that is, how far is the starting point from the end point.
The distance between the start and end points
miles
307,407 rounded to the nearest thousand is 307,000.... because it is closer to 307,000 then it is to 308,000
