mart [117]

<h3>Given :- </h3>

$\quad \qquad \bullet \quad \sf x = 3$

$\quad \leadsto \quad \sf \dfrac{3x - 5 ( 9 \times 3 )}{2}$

<h3>Solution :- </h3>

Let's Start :-

$\quad \leadsto \quad \sf \dfrac{3x - 5 ( 9 \times 3 )}{2}$

Putting the respective value of x we have ;

${ : \implies \quad \sf \dfrac{3\cdot 3- 5 (27 )}{2}}$

${ : \implies \quad \sf \dfrac{9- 135}{2}}$

${ : \implies \quad \sf - \dfrac{126}{2}}$

${ : \implies \quad \bf - 61}$

$\quad \qquad { \bigstar { \underline { \boxed { \pmb { \bf { \red { \underbrace { \therefore \dfrac{3x - 5 ( 9 \times 3 )}{2} = - 61}}}}}}}}{\bigstar}$

FinnZ [79.3K]

Answer:

We can be 95% confident that consumers spend between $4.04 and $15.96 less at Store A than the consumers spend at Store B.

Step-by-step explanation:

Confidence Intervals give an estimate as range of values for a statistic concerned at a <em>confidence level</em>.

In this case the statistic is the mean difference between Store A and Store B purchase amounts and the confidence level is 95%.

Confidence Interval can be calculated using M±ME where

M is the sample mean difference between Store A and Store B purchase amounts

ME is the margin of error from the mean
