Confidence intervals for the population mean μ and population proportion p becomes narrower as the size of the sample increases.
As,the sample size increases,standard error decreases,so margin of error decreases and hence width of CI decreases.
Explanation:
According to the Newton's second law of motion,
F = ma
=
or, v =
=
= 12.049 m/s (+x direction)
Therefore, we can conclude that the velocity at the end of this interval is 12.049 m/s.
