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.
- <em>combined mass in scientific notation can be written as</em> 97.2×
kg
- Scientific notation can be regarded as a way of writing very large as well as very small numbers.
Mars of mass= (6.42x
kg )
Mercury= (3.3x kilograms)
Then we add together
(6.42x )+ (3.3x) kilograms.
= 9.45 × kilograms
Therefore, combined mass in scientific notation can be written as 97.2× kg
