Explain why the margin of error determines the accuracy with which a sample mean estimates a population mean.

Answers

Answer 1

Answer:

The answer is below

Step-by-step explanation:

Given that Margin of error is a term applicable in statistics that describe the extent of error calculated from a random sampling analysis or research.

It, therefore, determines the accuracy with which a sample mean estimates a population mean with a predefined degree of confidence, the population means is within the margin of error of the sample mean.

This implies that a higher margin of error than the specified degree of confidence will equate that the results of such a survey are not reliable.

the rate of change of function g from x=-3 to x=-1 is the same as it is from x=-1 to x=1. Is function g linear, quadratic or exponential?

Answers

Answer:

We conclude that we conclude that the rate of change of a linear function g from x=-3 to x=-1 is the same as it is from x=-1 to x=1.

Thus, the function is linear.

Step-by-step explanation:

We know that the rate of change remains constant for a linear function.

In other words, the rate of change does not change for the entire domain of a linear function.

Comparing with the slope-intercept form

The slope-intercept form of a linear function is

[tex]y = mx+b[/tex]

where m is the slope or rate of change

For example, considering the linear function

[tex]y = 6x + 4[/tex]

Then the average rate of change is 6 over any interval selected.

Therefore, we conclude that we conclude that the rate of change of a linear function g from x=-3 to x=-1 is the same as it is from x=-1 to x=1.

Thus, the function is linear.

A light bulb consumes 9900 watt-hours in 5 days and 12 hours. How many watt-hours does it consume per day?

Answers

5 days and 12 hours = 132 hours

9900 total watts / 132 hours = 75 watts per hour

Since the light bulb consumes 75 watts an hour, we need to multiply 75 watts by 24 hours, to figure out how many watts are consumed in a day.

75 watts per hour x 24 hours = 1,800 watt-hours per day

What is an equation of the line that passes through the point (6,3) and is parallel to
the line x + 3y = 24?

Answers

Answer:

x + 3 y = 15

Step-by-step explanation:

line is paralle that means that coefficient next to x mand y must be the same

so the equation of the line will be

x + 3y = a

we have to find a, we know that line passes throgh (6,3) so

6 + 3 * 3 = a

a = 15

the line has an equation

x + 3 y = 15
