Y intercept is (0,-7). slope is 2.
Change the function to y=mx+b format first. m=slope and plug in 0 as x to get y intercept.

Answer:
p = - 2
Step-by-step explanation:
Given
n = 2 + 6m ← substitute m = - into the expression
n = 2 + 6(- ) = 2 - 3 = - 1
Thus
p = =
= - 2
Using the normal distribution, it is found that 0.0329 = 3.29% of the population are considered to be potential leaders.
In a <em>normal distribution</em> with mean and standard deviation
, the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
In this problem:
- The mean is of 550, hence
.
- The standard deviation is of 125, hence
.
The proportion of the population considered to be potential leaders is <u>1 subtracted by the p-value of Z when X = 780</u>, hence:
has a p-value of 0.9671.
1 - 0.9671 = 0.0329
0.0329 = 3.29% of the population are considered to be potential leaders.
