Question 1: You keep track of the daily hot chocolate sales and the outside temperature each day. The data you gathered is shown in the data table below. (image attached)

Make a scatterplot of the data.

Take your time making the answer, just please make sure it is right. I just need it by tomorrow. Just doing a rough sketch would be so amazing. Thank you!

this is my 4th time posting this question because every one just wants my points and won't attach an image :(

(A) The scatter plot is attached below.

(B) The outlier is at (189, 16°F).

(C) There is a negative correlation.

(D) The dependent variable is sales and independent variable is the temperature.

Step-by-step explanation:

The data provided for Hot chocolate sales and outside temperatures is as follows:

Sales (Y)  Temperature (X)

100          92

213                88

830          54

679          62

209          85

189           16

1110          52

456          65

422          68

235          89

199          91

(A)

The scatter plot is attached below.

(B)

A cluster is a collection of points or values at one place.

On the scatter plot there is a cluster of three values between the temperatures 80°F to 100°F.

An outlier is a value that is very different from the other values in a data set. It is either too small or too large.

There is an outlier present in the provided data set.

The outlier is at (189, 16°F).

(C)

The point on the scatter plot are downwards sloping.

This implies that there is a negative relationship between the variables temperature and sales.

Thus, there is a negative correlation.

(D)

Dependent variables are those variables that are under study, i.e. they are being observed for any changes when the other variables in the model are changed.

Independent variables are the variables that are being altered to see a proportionate change in the dependent variable.

In this case the data represents the sales of hot chocolate according to the temperature outside.

So, the dependent variable is sales and independent variable is the temperature.

This is because as the temperature decreases the sales of hot chocolate increases.

i still want free points lol

Step-by-step explanation:

Here's the scatterplot:

thus, the first answer choice, y = sec x, is the correct one
