trasher [3.6K]2 years ago

Answer:

y=-1/2x+b

Step-by-step explanation:

we can see that the line is going through (0,9) and the closest point is goes through next is (1,7).

so knowing that y=mx+b, we can plug in numbers to this equation.

take on of the points, and find the slope. the slope is -1/2.

so we would plug in one of our points plus the slope into our equation:

7=-1/2(1) +b

now we do the algebra and find that 7 1/2 =b.

so now the equation is y=-1/2x+b.

A study was done on the timeliness of flights (on-time vs. delayed) of two major airlines: StatsAir and AirMedian. Data were col
Scorpion4ik [409]

Answer:

The answer is Option E; both B and C are correct

Step-by-step explanation:

Both (b) and (c) are correct. Simpson's paradox is a paradox in which a trend that appears in different groups of data disappears when these groups are combined, and the reverse trend appears for the aggregate data. This result is often encountered in social-science and medical-science statistics, and is particularly confounding when frequency data are unduly given causal interpretations. Simpson's Paradox disappears when causal relations are brought into consideration.

Now, this question is an example of Simpsons paradox because the groups of collected data over a period of time from five major cities showed a trend that StatsAir does better overall, but this trend is reversed when the groups are studied separately to show that air median does better.

So, option B is correct.

Also, City is a variable that influences both the dependent variable and independent variable, causing a spurious association. That is it is the cause of why the 2 results are biased. Thus, city is a lurking variable.

So, option C is also correct

PLZ HELP MARKIN BRAINIEST!!!
Lady_Fox [76]

Answer:

Step-by-step explanation:

The first question is asking you how many visitors there were, using the function model provided, when x = 0.  Filling that in gives you:

y=18,582(.90)^0

Anything to the 0 power = 1, so

y = 18,582(1) and

y = 18,582

The second question is asking you how many visitors there were on the 9th weekend, when x = 9:

y=18,582(.90)^9 and

y=18,582(.387420489) so

y = 7199

The last question is asking on what weekend (unknown x) are there

y = 15.051 visitors.  That requires using a log to solve for x.  Set it up first:

15,051=18,582(.90)^x

Start by dividing both sides by 18,582 to get:

.8099773975=(.90)^x

Now we need to take the log of both sides to get that x out from its exponential position.  By taking the log of the right side, we are given the ability to bring the x down in front:

log(.8099773975) = x log(.90)

Now divide both sides by log(.90) to get

x = 2.000

That means that on the second weekend, there were approximately 15,051 visitors.

) The following scatterplot shows the percentage of the vote a candidate received in the 2016 senatorial elections
lys-0071 [83]

The critical values corresponding to a 0.01 significance level used to test the null hypothesis of ρs = 0 is (a) -0.881 and 0.881

<h3>How to determine the critical values corresponding to a 0.01 significance level?</h3>

The scatter plot of the election is added as an attachment

From the scatter plot, we have the following highlights

  • Number of paired observations, n = 8
  • Significance level = 0.01

Start by calculating the degrees of freedom (df) using

df =n - 2

Substitute the known values in the above equation

df = 8 - 2

Evaluate the difference

df = 6

Using the critical value table;

At a degree of freedom of 6 and significance level of 0.01, the critical value is

z = 0.834

From the list of given options, 0.834 is between  -0.881 and 0.881

Hence, the critical values corresponding to a 0.01 significance level used to test the null hypothesis of ρs = 0 is (a) -0.881 and 0.881
