Find an equation in slope-intercept forma for the línea with slope -12 and y-intercept=1/2

jolli1 [7]

Answer:

Option D

Step-by-step explanation:

Slope intercept is:

$y=mx+b$

m - slope

b - y-intercept.

The slope in the question is -12. The y-intercept is 1/2.

Plug in the values:

$y=mx+b\rightarrow \boxed{y=-12x+\frac{1}{2}}$

A study is conducted to determine how long a person will wait on hold on a telephone call before hanging up. A sample of 1000 pe

babymother [125]

Answer:

CI = ( 0,539 ; 0,599)

Step-by-step explanation:

The proportion p₀ of person that hung up the phone in the first minute of waiting is:

p₀ = 569/1000 p₀ = 0,569 p₀ = 56,9 %

Then q₀ = 1 - 0,569 q₀ = 0,431 q₀ = 43,1 %

Sample size is n = 1000

A 95 % CI is: α = 5 % α = 0,05 a/2 = 0,025

In z-table we look z ( score ) for 0,025 z = ± 1,96

Now CI for proportion is:

p₀ - z (α/2) * √ (p₀*q₀ )/n < p < p₀ + z (α/2) * √ (p₀*q₀ )/n

we need to find out

z(α/2) * √ (p₀*q₀ )/n = 1,96*√ ( 0,569*0,431)/1000 = 1,96 *0,01566 =0,03

Then

CI ( 95%) = 0,569 ± 0,03 = ( 0,569 - 0,03 ; 0,569 + 0,03)

CI = ( 0,539 ; 0,599)
