Answer: a) Unimodal and symmetric
b) 0.26
c) 0.038
Step-by-step explanation:
Given: Sample size of investors (n)= 131
True proportion of smartphone users(p) =26%
a) Since sampling distribution for the sample proportion is approximately normal when n is larger.
Normal distribution is Unimodal and symmetric.
So correct option : Unimodal and symmetric
b) mean of this sampling distribution = p = 0.26
c) standard deviation of the samplingdistribution =
The point-slope form of the equation of the line through the given points through: (-3,-1) and (-2,5) is y + 1 = 6x + 18
<u>Solution:</u>
Given, two points are (-3, -1) and (-2, 5)
We have to find that a line that passes through the given two points.
First let us find the slope of the line that passes through given two points.
<em><u>The slope of line "m" is given as:</u></em>
Now, let us find the line equation using point slope form
where m is slope
Hence the point slope form is y + 1 = 6x + 18
