Construct a scatterplot and identify the mathematical model that best fits the data. Assume that the model is to be used only fo

r the scope of the given data and consider only linear, quadratic, logarithmic, exponential, and power models. Use a calculator or computer to obtain the regression equation of the model that best fits the data. You may need to fit several models and compare the values of R2.
y = –477.38 + 237.66 ln x


y = –109.41 + 14.59x


y = 11.46 e1.107x


y = 0.45x1.903

450 people are randomly selected at grocery stores across the state and surveyed on the amount of money they are spending at the
____ [38]

Answer:

Step-by-step explanation:

Sample variance when large number of samples are drawn we have tend to become a normal distribution.

Variance of the sample is different since variance

Var(x) = E(x^2)-{E(x)}^2

is the formula used for finding the variance of any sample.

But sampling distribution of variance requires repeating this process with the different samples several times.

So option A is not right

B is also not correct, C is wrong

D.The sampling distribution of the mean requires multiple samples to be compared. However, in this situation you are looking for the variance, so finding the sample variance is the same as investigating the sampling distribution of the variance.

is correct

find the equation of the straight line passing through the point (3, 3) which is perpendicular to the line y=-1/2x-4
maw [93]

Answer:

y = 2x - 3

Step-by-step explanation:

The negative recipricol is -1/(-1/2) = 2

Use point-slope equation:

y-y1 = m(x-x1)

x1 = 3, y1=3

y-3 = 2(x-3)

y-3 = 2x-6

<u>y = 2x-3</u>
