F(x) is written in mx + b form for linear equation. so we have m =2 and b = -1
m represents the slope so the slope is 2
it means that the length is 5 times the width
<span>The sample proportion of the the students that took fewer than the mean number of electives is given by the number of people who took less that the mean number of electives (i.e. 7.63) divided by the total number of students in the sample (i.e. 19).
The total number of people who took less than 7.63 electives is 10.
Therefore, the required sample proportion is 10 / 19. </span>

Step-by-step explanation:
Hello!
You have sample of n=7 with mean X[bar]= 1403 and standard deviation S=27 and are required to estimate the mean with a 95%CI.
Asuming this sample comes from a normal population I'll use a stuent t to estimate the interval (a sample of 7 units is too small for the standard normal to be accurate for the estimation):
[X[bar]±
*
]

[1403±2.365*
]
[1378.87;1427.13]
The margin of error is the semiamplitude of the interval and you can calculate it as:

With a confidence level of 95% you'd expect that the real value of the mean is contained by the interval [1378.87;1427.13], the best estimate of the mean value is expected to be ± 24.13 of 1403.
I hope it helps!
