The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average or we can say a median is a point in the horizontal line having
multiple points such that the sum of difference of this point to all other points is minimum. For example,
consider 1 345 7 to be the points on a horizontal line then 4 will be the point through which the sum of
difference of all other points is minimum.
Similarly, a median in a 2d plane is a point such that the sum of the manhattan distance of this point from all
other points is minimum.
Manhattan distance for points P1(x1,71) and P2(x2.72) is [x1-x2] + [y1-y21.
Consider there are 9 points in the 2-D planes as (2,2), (4,4), (6,6)(20,20). How many medians does exist in this
situation?
A:9
B:4
C:1
D:12​

Which data set has a greater spread? why? set a: {38, 12, 23, 48, 55, 16, 18} set b: {44, 13, 24, 12, 56} has a greater spread because .

The ratio of the measures of the three angles in a triangle is 2: 9: 4. find the measures of the angels

Amachine that produces a special type of transistor (a component of computers) has a 2% defective rate. the production is considered a random process where each transistor is independent of the others. (a) what is the probability that the 10th transistor produced is the first with a defect? (b) what is the probability that the machine produces no defective transistors in a batch of 100? (c) on average, how many transistors would you expect to be produced before the first with a defect? what is the standard deviation? (d) another machine that also produces transistors has a 5% defective rate where each transistor is produced independent of the others. on average how many transistors would you expect to be produced with this machine before the first with a defect? what is the standard deviation? (e) based on your answers to parts (c) and (d), how does increasing the probability of an event a↵ect the mean and standard deviation of the wait time until success?
