Method 1:
In order to solve for this, we have to find out how many words Ryan can type in one minute first.
can be simplified into
(This is just normal simplifying, all you had to do was divide both sides by 12)
Now that we have our rate, , we can figure out how many words Ryan can type in 20 minutes
* 20/20 =
Ryan can type 1000 words in 20 minutes
Method 2:
You can use two fractions in order to solve this equation:
=
The 'x' on the right is a variable because we don't know what the number is.
Simplify:
=
Cross multiply:
1 * x = 50 * 20
x = 1000
Ryan can type 1000 words in 20 minutes

Answer:
The confidence interval becomes wider.
Step-by-step explanation:
The general form of a confidence interval is:
The critical value is based on the confidence level.
The confidence level is the probability that the true parameter value falls within a specific interval. The basic and most used confidence levels are 90%, 95% and 99%.
The confidence interval is directly proportional to the confidence interval.
Confidence Interval ∝ Confidence Level
On increasing the confidence level the confidence level widens. And on decreasing the confidence level the confidence level gets narrower.
Thus, when Gina changes the confidence interval to 99% the confidence interval becomes wider.
