Answer:
october
Step-by-step explanation:
the months are going 3 at a time.
Using a graphing tool
Let's graph each of the cases to determine the solution of the problem
<u>case A)</u>
see the attached figure N
The range is the interval--------> (0,∞)
therefore
the function is not the solution
<u>case B)</u>
see the attached figure N
The range is the interval--------> (0,∞)
therefore
the function is not the solution
<u>case C)</u>
see the attached figure N
The range is the interval--------> (-∞,3)
therefore
the function is the solution
<u>case D)</u>
see the attached figure N
The range is the interval--------> (-3,∞)
therefore
the function is not the solution
<u>the answer is</u>
Answer:
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Answer:
A. 110 pounds,
C. 281 pounds
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
A measure is said to be an outlier if it has a pvalue lesser than 0.05 or higher than 0.95.
In this problem, we have that:
A. 110 pounds,
has a pvalue of 0.0179. So a weight of 110 pounds is an outlier.
B. 157 pounds,
has a pvalue of 0.702.
So a weight of 157 is not an outlier.
C. 281 pounds
has a pvalue of 0.9988.
So a weight of 281 is an outlier.
