The five-number summary for a set of data is given below. Min Q1 Median Q3 Max 53 61 63 72 76 What is the interquartile range of the set of data?

(IQR) Interquartile range = 74 - 57 = 17

Step-by-step explanation:

Arrange the data set from least to greatest. (which already is in a least to greatest form)

53, 61, 63, 72, 76

find the median (the middle number)

Median: 63

then find both lower and upper quartile:

Lower quartile: 53 + 61 = 114/2 = 57

Upper quartile: 72 + 76 = 148/2 = 74

Formula for the interquartile range:

(IQR) interquartile range: upper quartile - lower quartile = answer

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
