Answer:
a) True
Step-by-step explanation:
Repeated samples are a type of samples that are used to determine the features or characteristics or a given set of data.
In repeated samples, statistical techniques are applied whereby two samples that have similar characteristics are tested or analysed under different conditions.
Repeated samples can also be called matched or paired samples.
In repeated samples , we have what we refer to as confidence intervals. These are intervals whereby the true and correct value of certain parameters such as mean, the standard deviation of a given data or distribution is determined. We have confidence interval levels of 90%, 95% and 99%.
In repeated samples, approximately 99% of all differences in sample means will fall within the bounds of the interval already computed.
The answer is 3:5
to find it, divide both sides of 18:30 by the GCF
the GCF of 18 and 30 is 6
so, 18/6=3 and 30/6=5
the simplified ratio is 3:5
15x+$38.50=$100
x being however much she can spend on each friend
x= $12.30 if you need that too
Answer:
-90
Step-by-step explanation:
1/5 = 0.2
18/0.2 = 90
90*-1 = -90
