Answer:
<em>The equation of the straight line in point - slope form</em>
<em>y +1 = -2 ( x-2)</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given points are C( 2,-1) and D(1,1)
Slope of the line
m = -2
<u>Step(ii):-</u>
Equation of the straight line passing through the point ( 2,-1) and having slope
m =-2
y - y₁ = m ( x- x₁)
y - (-1) = -2 ( x-2)
y +1 = -2 ( x-2)
<u><em>Final answer:-</em></u>
<em>The equation of the straight line</em>
<em>y +1 = -2 ( x-2)</em>

Answer:
P (x≥ 57) = 6.7789 e^-8
Step-by-step explanation:
Here n= 100
p = 31/100 = 0.31
We formulate the null hypothesis that H0: p= 0.31 against the claim Ha: p≠0.31
The significance level is chosen to be ∝= 0.05
The test statistic x to be used is X, the number U.S. residents is to be taken which is at least 57
The binomial calculator gives the
P (x≥ 57) = 6.7789 e^-8
IF ∝= 0.05 then ∝/2 = 0.025
We observe that P (x≥ 57) is less than 0.025
Hence we reject H0 and conclude that p ≠0.31
This is true because for normal distribution the median = mean which is usually the 50 % of the data.
