Consider the hypothetical study described below. Based solely on the information​ given, do you have reason to question the resu
Bezzdna [24]

Answer:

B. ​Yes, there is reason. The TV audience might not be representative of the population.

Step-by-step explanation:

The question "Do you support new national mileage standards for​automobiles?" is asked to the TV audience.

Therefore those who will voted are the ones who are watching the TV show. We do not know the rate of people who do not watch TV or who do not watch that TV talk show in the population.

Thus the results cannot represent the whole population

The delivery times for all food orders at a fast-food restaurant during the lunch hour are normally distributed with a mean of m
UkoKoshka [18]

Answer:

Let X the random variable that represent the delivery times of a population, and for this case we know the distribution for X is given by:

X \sim N(14.7,3.7)  

Where \mu=14.7 and \sigma=3.7

Since the distribution of X is normal then we know that the distribution for the sample mean \bar X is given by:

\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})

And we have;

\mu_{\bar X}= 14.70

\sigma_{\bar X} =\frac{3.7}{\sqrt{40}}= 0.59

Step-by-step explanation:

Assuming this question: The delivery times for all food orders at a fast-food restaurant during the lunch hour are normally distributed with a mean of 14.7 minutes and a standard deviation of 3.7 minutes. Let R be the mean delivery time for a random sample of 40 orders at this restaurant. Calculate the mean and standard deviation of \bar X Round your answers to two decimal places.

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the delivery times of a population, and for this case we know the distribution for X is given by:

X \sim N(14.7,3.7)  

Where \mu=14.7 and \sigma=3.7

Since the distribution of X is normal then we know that the distribution for the sample mean \bar X is given by:

\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})

And we have;

\mu_{\bar X}= 14.70

\sigma_{\bar X} =\frac{3.7}{\sqrt{40}}= 0.59

In the equation y=mx+b, what does the x stand for? And, in the equation y=3x+6 how would I solve for y?
ladessa [460]

Answer:

x stays x in both equations so x stands for x

Step-by-step explanation:

y=3x+6

you can put this into a graphing caculator or draw it yourself.

6 is the y value when x equals 0. and the 3 represents the slope so then it is solved for any y value
