A local statistician is interested in the proportion of high school students that drink coffee. Suppose that 20% of all high school students drink coffee. What is the probability that out of these 75 people, 14 or more drink coffee?

the probability that out of these 75 people, 14 or more drink coffee is 0.6133

Step-by-step explanation:

Given that:

sample size n = 75

proportion of high school students that drink coffee p = 20% = 0.20

The proportion of the students that did not drink coffee = 1 - p

Let X be the random variable that follows a normal distribution

X N (n, p)

X   N (75, 0.20)

= 75 × 0.20

15

Now ; if 14 or more people drank coffee ; then

From the standard normal z tables; (-0.288)

the probability that out of these 75 people, 14 or more drink coffee is 0.6133

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

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
