What can she infer about the wingspans of the two types of birds?
Type 1: {18, 24, 20, 22, 26}
Type 2: {24, 21, 19, 26, 30}
A.
Type 1 and Type 2 birds have similar wingspan distributions.
B.
Type 1 and Type 2 birds have somewhat similar wingspan distributions.
C.
Type 1 birds and Type 2 birds do not have similar wingspan distributions.
D.
Type 1 birds and Type 2 birds have identical wingspan distributions.
Answer:
Step-by-step explanation:
The given data set for type 1 of birds is:
Type 1: {18, 24, 20, 22, 26}
Type 2: {24, 21, 19, 26, 30}
Mean of the type 1 data is:
Data
18 16
24 4
20 4
22 0
26 16
Now, mean average of squares is:
Standard deviation=
Now, the difference of mean and its standard deviation of type 1 data set is:
=22-2.828
Difference =19.172
The given data set for type 2 of birds is:
Type 2: {24, 21, 19, 26, 30}
Mean of the type 2 data is:
Data
24 0
21 9
19 25
26 4
30 36
Now, mean average of squares is:
Standard deviation=
Now, the difference of mean and its standard deviation of type 2 data set is:
=24-3.84
Difference=20.16
Since, the difference of mean and standard deviation of both type 1 and type 2 data set is different, therefore, Type 1 birds and Type 2 birds do not have similar wingspan distributions.
Hence, option C is correct.
Answer:
Type 1 and Type 2 birds have similar wingspan distributions.
Step-by-step explanation:
e=Evelyn's age
v=victor's age
A. e=v+9
B. v=e+9
C. e=v-9
D. e+v=9
Since e represents evelyn ege, hence the equation that tells you how to find Evelyn's age if you know Victor's age is e = v + 9
These are equation containing unknown variables
If Evelyn was 9 when her brother Victor was born, hence;
Victors age = v
Evelyn age = v + 9
Substitute both equations
Since e represents evelyn ege, hence the equation that tells you how to find Evelyn's age if you know Victor's age is e = v + 9
