Answer:
The 90% confidence interval is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 200
The number of people that watched the educational television is 
Generally the sample proportion is mathematically represented as
=> 
From the question we are told the confidence level is 90% , hence the level of significance is
=> 
Generally from the normal distribution table the critical value of 
is
Generally the margin of error is mathematically represented as
=> 
=> 
Generally 95% confidence interval is mathematically represented as
=> 
=>

Answer:
3.2 feet
Step-by-step explanation:
The equation 
shows the height of water [
] and horizontal distance [
].
<em>Given the </em><em>horizontal distance is 4 feet</em><em>, they want to know the height.</em>
<em>Simply put 4 in of the equation and solve for . So,</em>
<em>
</em>
So, the height of the water was 3.2 feet above the ground.
I used mental math and it took a long time, but I got the answer of 2,499.
