Using the t-distribution, it is found that the 99% confidence interval for the difference is (0.058, 3.462).
We are given the <u>standard deviation for the samples</u>, hence, the t-distribution is used to solve this question.
The standard errors are given by:
For the distribution of differences, the <u>mean and the standard error</u> are given by:
The interval is given by:
The critical value for a <u>two-tailed 99% confidence interval</u> with 18 + 18 - 2 = <u>34 df</u> is t = 2.7284.
Then:
The 99% confidence interval for the difference is (0.058, 3.462).

Hi there!
The general equation of a slope-intercept line is :
y = mx + b
Where "m" is the slope and "b" is the y-intercept.
Since your equation is already in the right form, you can easily see that your "m" is equal to -4, which is the slope of the line.
Your answer is: The slope of the line is -4.
There you go! I really hope this helped, if there's anything just let me know! :)
Add them together since they're already in area unit
Hello!
The person started working at 8:30 and stopped at 11:45 for lunch. That means that person worked 1 hour and 15 minutes before taking a lunch break.
The lunch break doesn't count because the person wasn't "working" then.
Next, this person worked from 12:30 to 5:15, which means they worked 4 hours and 45 minutes.
Add this up with the 1 hour and 15 minutes from before:
4 h 45 min + 1 h 15 min = 6 hours
This person worked a total of 6 hours.
Answer:
First, write 80% as 80100. Then write an equivalent ratio that has the answer in the numerator and 200 in the denominator. 100 x 2 is 200, so 80 x 2 will be the answer. 80 x 2 = 160. The answer is $160.
