nalin [4]3 years ago
6 0

Answer:

1. $18.74x + $20 + $30

Estimated: 3x + 20 + 30 I THINK not completely sure on this estimated one.

2. is X x 2 - 9

3. is -1x + 15, step by step: group like terms: (6x - 7x) + (9 + 6) which would be -1x + 15

4. is (8n - 5.5) x 2 = 16n - 11

(5.5n + 10) x 2 = 11 + 20

group like terms: (-11 + 11 + 20) (16n) = 20 + 16n I think

5. is 1/7n + 31, second bar is 5/7n - 22, third bar is 1/7n + 26

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

ivolga24 [154]
Answer:
120
Step-by-step explanation:
To estimate the value, you round the digits to the nearest 10 , or the nearest 2 significant figures, in this case, 40.16 is rounded to 40 and 2.970201 is rounded to 3. This gives us 40 * 3 = 120
