A major car dealership has several stores in a big city. The owner wants to determine if there is a difference in the proportion

Gemiola [76]

Answer:

confidence interval = ( -0.38 , 0.08 )

Step-by-step explanation:

Given data :

n1 = 55 , n2 = 60 ,

Let P1 ( proportion of SUV sales at store A ) = 30 / 55 = 0.55

P2 ( sample proportion of SUV sales at store B ) = 42/60 = 0.70

The Z-value at 99% confidence Interval = 2.58

<u>Determine the 99% confidence interval for difference in proportion</u>

applying the formula below

( P1 - P2 ) ± Z ( $\sqrt{p1( 1-p1)/n1 + p2(1-p2)/n2}$

Input values above into equation

confidence interval = ( -0.38 , 0.08 )
