120/6=20 20*10=200
The answer is 200
Answer:
A 99% confidence interval will be wider than a 95% confidence interval
Step-by-step explanation:
From the question we are told that
The 95% confidence interval for for the mean foot length for students at the college is found to be 21.709 to 25.091 cm
Generally the width of a confidence interval is dependent on the margin of error.
Generally the margin of error is mathematically represented as
From the above equation we see that
Here 
is the critical value of the half of the level of significance and this value increase as the confidence level increase
Now if a 99% confidence level is used , it then means that the value of
will increase, this in turn will increase the margin of error and in turn this will increase the width of the confidence interval
Hence a 99% confidence interval will be wider than a 95% confidence interval
Answer:
8:14, 12:27, 40:70
Step-by-step explanation:
Radius = 100m
Circumference of a circle = 2πr
= 2 × π× 100
=628.31m
Answer:
The slope intercept form involves solving for y, such that the equation looks like this: y = mx + b, where m is a constant representing the slope of the line, and b is a constant representing the value of the y-intercept.
Starting with the equation x+2y=6 and subtracting x from both sides gives 2y = -x + 6.
If we then divide each term by 2, we get the final result of y = -1/2x + 3.
Here we see that the slope (m) is equal to -1/2, and the y-intercept (b) is 3.
