Answer:
A) classify the value 1.2 as an outlier, because it is more than 1.5 × IQR below the first quartile.
Correct we satisfy that 1.2 <1.7 the lower limit
Step-by-step explanation:
Assuming this complete question: A violin student records the number of hours she spends practicing during each of nine consecutive weeks:
6.2 5.0 4.3 7.4 5.8 7.2 8.4 1.2 6.3
For this case we need to sort the data first on increasing way and we got:
1.2, 4.3, 5.0, 5.8, 6.2, 6.3, 7.2, 7.4, 8.4
For this case we have 9 values the median would be on the 5 position:
The first quartile would be 5 since we analyze 1.2, 4.3, 5.0, 5.8, 6.2 and the middle point is 5.0
The third quartile would be 7.2 since we analyze 6.2, 6.3, 7.2, 7.4, 8.4 and the middle point is 7.2
Then the interquartile rnage would be:
And
The lower limit on this case would be:
And our value is 1.2 is lower than the lower limit 1.7
Considering the smallest data value (1.2) and using the 1.5 × IQR rule, we would:
A) classify the value 1.2 as an outlier, because it is more than 1.5 × IQR below the first quartile.
Correct we satisfy that 1.2 <1.7 the lower limit
B) not classify the value 1.2 as an outlier, because it is not more than 1.5 × IQR below the first quartile.
False 1.2 is more than 1.5 IQR below the first quartile
C) classify the value 1.2 as an outlier, because it is more than 1.5 × IQR below the median.
False, we analyze if is an outlier comparing with the Q1 or Q3 not with the median
D) classify the value 1.2 as an outlier, because it is more than 1.5 × IQR below the mean.
False we analyze if is an outlier comparing with the Q1 or Q3 not with the mean
Answer:
If the signs of rational numbers are same, then the answer is positive.
If the signs of rational numbers are different, then the answer is negative.
Step-by-step explanation:
Consider the provided information.
A: When multiplying or dividing rational numbers, when will the answer be positive?
If we are multiplying or dividing rational numbers the answer will be positive if and only if both the rational numbers have same sign.
For example: Multiply 2 and 4.
2×4=8 (same sign)
or
Multiply -2 and -4.
-2×-4=8 (same sign)
8 is a positive rational number.
Now divided 2 and 4.
or
Divided -2 and -4.
1/2 is a positive rational number.
Hence, If the signs of rational numbers are same, then the answer is positive.
B: When multiplying or dividing rational numbers, when will the answer be negative?
If we are multiplying or dividing rational numbers the answer will be negative if and only if both the rational numbers have different sign.
For example: Multiply 2 and -4.
2×-4=-8 (different sign)
or
Multiply -2 and 4.
-2×4=-8 (different sign)
-8 is a negative rational number.
Now divided 2 and -4.
or
Divided -2 and 4.
-1/2 is a negative rational number
Hence, If the signs of rational numbers are different, then the answer is negative.
