The value (y2) of r = 1/2.
This question relates to equation of a straight line but we are looking for the slope in this case.
<h3>Slope</h3>This is the ratio to which we measure the change along the y-axis to the change along the x-axis. The formula is given as
Data given;
- x1 = 3
- x2 = -3
- y1 = 5
- y2 = r
- m = 34 or 3/4
Substitute the values into the equation and solve for the unknown
NB; we are assuming that the slope here is 34 and not 3/4.
cross multiply both sides and make r the subject of formula
the value of r = -199.
This is not mathematically obtainable and we would use 3/4 as the value of slope
The most logical value of r = 1/2

Step-by-step explanation:
Given that you conduct simple random sampling of 20 students in a school with a population of 300 students to determine how many students are in each ride-share (carpool) on the way to school every day to get a good idea of who would use the app.
The following data are collected:
6 5 5 5 3 2 3 6 2 2 5 4 3 3 4 2 5 3 4 5
We find from the data the following summary
Mean 3.85
Standard Error 0.30153118
Median 4
Mode 5
Standard Deviation 1.348488433
Sample Variance 1.818421053
Kurtosis -1.29567952
Skewness 0.014666866
Range 4
Minimum 2
Maximum 6
Sum 77
Count 20
Confidence Level(95.0%) 0.631112012
Margin of error = 0.6311
Hence confidence interval would be (Mean - margin of error, mean + margin of error)
=
