Step-by-step explanation: A coordinate grid has two perpendicular lines, or axes (pronounced AX-eez), labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis. The point where the x- and y-axis intersect is called the origin

There is no prior information about the proportion of Americans who support the gun control in 2018. If we want to estimate 99%

Romashka-Z-Leto [24]

Answer: 13

Step-by-step explanation:

If the prior population proportion is unavailable then the formula to find the sample size is given by :-

$n=0.25(\dfrac{z^*}{E})^2$

, where z* = Critical z-value

E = margin of error

Let p be the proportion of Americans who support the gun control in 2018.

As per given , we have

Confidence level = 99%

The critical z-value for 99% confidence interval is 2.576 ( BY z-table)

Margin of error : E= 0.36

Since there no prior information about the proportion of Americans who support the gun control in 2018.

So , the required sample size to estimate 99% confidence interval would be:

$n=0.25(\dfrac{2.576}{0.36})^2=0.25(7.16)^2$

$n=0.25(51.2656)=12.8164\approx13$

Hence, 13 Americans should be surveyed.

For a least squares regression line, the sum of the residuals is __________.

Westkost [7]

Answer:

d. always zero.

Step-by-step explanation:

A least squares regression line is a standard technique in regression analysis used to make the vertical distance obtained from the data points running to the regression line to become very minimal or as small as possible.

For a least squares regression line, the sum of the residuals is always zero.

Basically, residuals are used to measure or determine whether or not the line of regression is a good fit or match for the data by subtracting the difference between them i.e the predicted y value and the actual y value, for the x value respectively.
