The accompanying data represent the pulse rates (beats per minute) of nine students. Treat the 9 students as a population. Compute the z-scores for all the students. Compute the mean and standard deviation of these z-scores. Student Pulse z-score1 762 613 604 805 726 807 808 689 73Complete the table z-score (round to the nearest hundredth as needed)The mean of z-score is The standard deviation of the z-scores is?

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
