Answer:

Product B performed worse in the study because 86% failed to get relief with this product, whereas only 78% failed to get relief with Product A

Step-by-step explanation:

We are given the following in the question:

Product A:

Number of people,

n_1 = 50

Number of people who received relief,

x_1 = 11

Proportion of people who received relief from product A =

p_A = \dfrac{x_1}{n_1} = \dfrac{11}{50} = 0.22 = 22\%

Proportion of people who did not received relief from product A =

1 = p_A = 1 - 0.22 = 0.78 =78\%

Product B:

Number of people,

n_2 = 100

Number of people who received relief,

x_2 = 14

Proportion of people who received relief from product B =

p_B = \dfrac{x_2}{n_2} = \dfrac{14}{100} = 0.14 =14\%

Proportion of people who did not received relief from product B =

1 = p_B = 1 - 0.14 = 0.86=86\%

Product B performed worse in the study because 86% failed to get relief with this product, whereas only 78% failed to get relief with Product A

Elodia [21]

Answer:

Some number divided by 4

Step-by-step explanation:

The y stands for an unknown number, aka some number. The slash indicates division, so it would be some number divided by 4.

Question 3 (Essay Worth 10 points) (05.07 MC) The scatter plot shows the number of strawberries that have been picked on the far
solong [7]

It's not an accurate value for the data based on the scatter plot, r = 0.01 is not an accurate value for this data, because 0.01 means practically no correlation, while the points on the graph are moderately correlated

<h3>How to illustrate the information?</h3>

1. Part A:

Since the points in the scatter plot show a moderated upward trend, you must expect a correlation coefficient close to ± 0.5. A correlation coefficient of 0.01 is too close to 0, which would mean that the points are almost not correlated at all.

The correlation coefficients, r, measure the strength of the correlation of two variables and they can have values from - 1 to  1.

Here, r = - 1 is a perfect negative correlation as the points will adjust perfectly to a line with negative slope.

r =  + 1 is a perfect positive correlation: the points will ajdust perfectly to a line with positive slope.

r = 0 means that the variables are not correlated at all.

Hence, the closer to zero, the worse the correlation is, and that is what r = 0.01 means, but the graph shows other thing.

Therefore, the calculated value of r = 0.01 is not accurate for this scatter plot.

2. Part B.

A causal relationship means that the explanatory variable (the independent variable) is the cause of the dependent variable.

Hence, you must find a reasonable variable that can be the cause of the number of strawberries picked.

Thus, the scenario could be:

Amout of rainfall in mm (x)         Number of strawberries picked (y)

      100                                                     20

        50                                                     40

        25                                                     80

        12.5                                                  160

        6.25                                                 320

The amount of rainfall is the cause of the number of strawberries picked, and you could find a model that relates both variables.

Use the drawing tool(s) to form the correct answer on the provided graph.
lorasvet [3.4K]

9514 1404 393

Answer:

  see below

Step-by-step explanation:

Setting x=0, you can find the y-intercept:

  y = 4

Setting y = 0, you can find the x-intercept:

  2x = 4

  x = 2

The boundary line can be drawn through these intercept points, (0,4) and (2,0). Because the "equal to" case is not included, the boundary line will be dashed.

The y variable is on the open side of the comparison symbol (y>), so the shading is above the boundary line. That is where y-values are greater than those on the line.

Quick problem to check!
Andrew [12]

To find the rate of change, also known as the slope, we can use the slope formula with these two given points.

Point 1: (20, 25)

Point 2: (50, 40)

(40 - 25) / (50 - 20)

15 / 30

0.5

The rate of change of this function is $0.50 / lb.

Hope this helps!! :)
