Answer:
this would represent a strong negative
Step-by-step explanation:
on a correlation line you have strong negatives,weak negatives,none,weak positives, and strong positives.Since the coefficient is a hand negative, focus on the left side. A weak negative is -0.5 greater than or equal to so since -0.94 is less than -0.5 it advances on to the next category of the correlation line, thus resulting in the correlation coefficient to be a strong negative.

Answer:
The 99th percentile for a man’s arm span is 80.47 inches.
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.
In this problem, we have that:

99th percentile
X when Z has a pvalue of 0.99. So X when Z = 2.327.




The 99th percentile for a man’s arm span is 80.47 inches.
Answer:
b/a
27= b
3= a
I used a and b since it's algebraic
The product is -8*5=-40& sum is -8+5=-3
