The sample size is the number of people.
You can get the sample size by counting the completion times for each.
Sample size of men = 19
Sample size of women = 34
The mean time is the average time, so you need to add all the times for the men and divide it by the number of men and then the same for the women:
Mean time for men = 3129 / 19 = 164.68 seconds
Mean time for women = 5834 / 34 = 171.59 seconds.
The mean time taken by men is less than the women.
Answer:
y = -2x + 7 is the equation if that's what you are asking for.
Answer:
6 people
Step-by-step explanation:
75% of 8 is 6
multiply 8 by the decimal .75
(Sorry if I get something wrong, it’s straining my eyes to see what letter) 1. A 2. U 3. S 4. J 5. I 6. M 7. H 8. B 9. Y 10. L
To find where a coordinate is on a graph you need to start with the first number (x) (let’s say the coordinate is (2, -3), so 2) and find where it is ( you always find where the first number is on the x-axis and the second number on the y, remember that by x, y and x comes first.) Then, you need to find the second number (-3) then you need to find where they meet. So 2, -3 is on the letter I.
To find what coordinates a point that’s already been plotted is to see, for example, L, the two numbers that meet where L is are -4, -3, remember whatever was on the x axis comes first, -3, -4 is not the same.
Hopefully this makes sense, I don’t normally answer stuff.
