A car manufacturer is concerned that dealers conceal unhappy customers by keeping them out of surveys conducted by the factory.

8_murik_8 [283]

Answer:

Yes, the manufacturer can estimate the proportion of all customers at this dealership who feel that its service is exceptionally good.

No, the manufacturer cannot estimate, the proportion of customers who rated the service as exceptionally good, about the other dealerships.

Step-by-step explanation:

A sample of 65 customers from a dealership is selected and it is determined that 55% of the customers rated the service as exceptionally good.

According to the central limit theorem if a large random sample selected from an unknown population then the sampling distribution of sample proportion ( $\hat p$ ) follows a normal distribution.

Then the population proportion can be estimated by the sample proportion value.

That is, $p=\hat p=0.55$ .

Thus, the manufacturer can estimate the proportion of all customers at this dealership who feel that its service is exceptionally good using the sample proportion value of $\hat p=0.55$ .

Since the sample is selected from a specific dealership, he cannot estimate, the proportion of customers who rated the service as exceptionally good, about the other dealerships.

What is an equation of the line that passes through the point (2, -6) and is parallel

Karo-lina-s [1.5K]

keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

$x-2y=8\implies -2y=-x+8\implies y=\cfrac{-x+8}{-2} \\\\\\ y=\cfrac{-x}{-2}+\cfrac{8}{-2}\implies y=\stackrel{\stackrel{m}{\downarrow }}{\cfrac{1}{2}}x-4 \qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}$

so we're really looking for the equation of a line whose slope is 1/2 and passes through the point (2 , -6)

$(\stackrel{x_1}{2}~,~\stackrel{y_1}{-6})\qquad\qquad \stackrel{slope}{m}\implies \cfrac{1}{2} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-6)}=\stackrel{m}{\cfrac{1}{2}}(x-\stackrel{x_1}{2}) \\\\\\ y+6=\cfrac{1}{2}x-1\implies y=\cfrac{1}{2}x-7$

Circled step where the error has occurred explain why it's an error.

olga_2 [115]

The error is not there. The error is step 4. -34 becomes positive so it is not -51 it's 17. So the answer is 40/17
