Answer:
The reasonable range for the population mean is (61%, 75%).
Step-by-step explanation:
The interval estimate of a population parameter is an interval of values that consist of the values within which the true value of the parameter lies with a certain probability.
The mean of the sampling distribution of sample proportion is, 
.
One of the best interval estimate of population proportion is the 95% confidence interval for proportion,
Given:
n = 150
= 0.68
The critical value of <em>z</em> for 95% confidence level is:
Compute the 95% confidence interval for proportion as follows:
Thus, the reasonable range for the population mean is (61%, 75%).

Answer:
16
Step-by-step explanation:
Complementary angles are angles which add to 90 degrees. This means 4x + 26 = 90. Solve for x using inverse operations in the equation.
4x+26 = 90
4x = 64
x = 16
Answer:
0.395 kilometers
Step-by-step explanation:
Please consider the complete question.
On Martin's first stroke, his golf ball traveled 4/5 of the distance to the hole. On his second stroke, the ball went into the hole. Martin was standing 79 meters from the hole as he took his second stroke. How many kilometers from the hole was Martin when he started?
Let x represent the distance between hole and start point.
In 1st stroke ball traveled 4/5 of the distance, so 1/5 of the distance was remaining from 2nd stroke to hole. This means the 1/5 of whole distance between start point and hole is equal to 79 meters.
We can represent this information in an equation as:
Since our distance is in meters, so we will convert 395 meters into kilometers by dividing by 1000.
Therefore, Martin was 0.395 kilometers from the hole, when he started.
