Step-by-step explanation:
Answer:
12.04m = l
Step-by-step explanation:
We can use the Pythagorean theorem
a^2 + b^2 =c^2
where a and b are the legs and c is the hypotenuse
12^2 + 1 ^2 = l^2
144 + 1 = l^2
145 = l^2
Take the square root of each side
sqrt(145) = sqrt(l^2)
12.04159458 = l
To the nearest hundredth
12.04m = l
Answer:
Step-by-step explanation:
The confidence interval for the population mean x can be calculated as:
Where x' is the sample mean, s is the population standard deviation, n is the sample size and 
is the z-score that let a proportion of 
on the right tail.
is calculated as: 100%-99%=1%
So, 
Finally, replacing the values of x' by 308, s by 17, n by 15 and by 2.576, we get that the confidence interval is:
4x - 2 = 2x + 8
2x -2 = 8
2x = 10
x = 5
4(5)-2 = 2(5)+8
20-2 = 10+8
18 = 18
