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.

The equations of four lines are given. Identify which lines are perpendicular.
Maksim231197 [3]

Answer:

lines 1 and 3

Step-by-step explanation:

y = 2 is a horizontal line parallel to the x- axis

x = - 4 is a vertical line parallel to the y- axis

Then these 2 lines are perpendicular to each other

y = 15x - 3 ( in the form y = mx + c ) with m = 15

y + 1 = - 5(x + 2) ( in the form y - b = m(x - a) with m = - 5

For the lines to be perpendicular the product of their slopes = - 1

However

15 × - 5 = - 75 ≠ - 1

The 2 lines 1 and 3 are perpendicular
