Say a scholarship is randomly assigned to a subset of students (treated) and not to others (control). The two groups are ex-ante identical and the sample size is 10,000. Assume this sample size is large enough such that a normal approximation is appropriate. The average score of the treated group is 10 and the average score of the control group is 9.2. The variance of difference between the treated and control is 0.25 and the 95% critical value for normal approximation is 1.96.
1. Compute the 95% confidence interval of the effect of the scholarship on student performance.

c is the final answer! : )

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
