At a particular college, 78% of all students are receiving some kind of financial aid. the school newspaper selects a random sample of 100 students and 72% of the respondents say they are receiving some sort of financial aid. which of the following is true? (a) 78% is a population and 72% is a sample. (b) 72% is a population and 78% is a sample. (c) 78% is a parameter and 72% is a statistic. (d) 72% is a parameter and 78% is a statistic. (e) 78% is a parameter and 100 is a statistic.

(c) 78% is a parameter and 72% is a statistic

Step-by-step explanation:

78% of students are receiving financial aid.

Number of samples selected = 100

72% of the sample selected are receiving financial aid.

The population is a made up of all the individuals we want to collect information from (the students of a particular college)

The part of the population from which sample are taken is called the sample.

78% describes the entire population while 72% describes the sample(100 students)

A parameter is a descriptive measure for a population while a statistic is a descriptive measure for a sample. Therefore

78% is a parameter while 72% is a statistic (C)

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
