Answer:
(d) WEAK NEGATIVE ASSOCIATION.
Step-by-step explanation:
Pearson correlation (r) is defined as a factor which measures the linear dependence between two variables (x and y). It's also known as a parametric correlation.
Here, r = -0.19
Now, as r is NEGATIVE.
⇒ As the value of x increases , value of y decreases.
⇒There is a NEGATIVE ASSOCIATION.
Now as the value of r is between 0 and ( -1). So the factor of variation is very small.
Hence, it is WEAK NEGATIVE ASSOCIATION.
Answer:
24/100
=6/25
Step-by-step explanation:
I = Prnwhere I is the interest, P is the principal, r is the decimal equivalent of the given rate, and n is the number of years. In this item, we assume that n is equal to 1. Solving for the interests, $200: I = ($200)(0.03)(1) = $6 $150: I = ($150)(0.03)(1) = $4.5The difference between the two calculated interests is $1.5.
Therefore, you could have earned $1.5 more if you invested $200 rather than $150.
hope this helps (^>^)
answer : 0.125
explanation: it’s actually really easy all you have to do is
take the fraction and divide it like :
1/8 = 1 divided by 8 = 0.125
Answer:
Step-by-step explanation:
Since population std deviation is not known, we use t critical value for testing of hypothesis.
a) 90% conf level when n =28
df = 27, t critical = 1.706
b) 95% 28
df =27 and t critical = 2.052
c) 90% and 15
df =14 and t critical = 1.761
d) 95% and n =15
df =14: t critical = 2.145
