Find the sum of the following infinite geometric series, if it exists. 2/5+12/25+ 72/125...

1 answer:

6 0

Each time multiplied by 6/5
the common ratio is 6/5
since |6/5|>1, the series does not converge to a single number and the sum approaches positive infinity

there is no real number that the sum of this series approaches

All else being equal, if you cut the sample size in half, how does this affect the margin of error when using the sample to make

gizmo_the_mogwai [7]

Answer:

The margin of error is multiplied by $\sqrt{2}$

Step-by-step explanation:

margin of error (ME) from the mean can be calculated using the formula

ME= $\frac{z*s}{\sqrt{N} }$ where

z is the corresponding statistic of the given confidence level

s is the standard deviation of the sample (or of the population if it is known)

N is the sample size

Since margin of error is proportional with inverse of $\sqrt{N}$ ,

if we cut the sample size in half, the margin of error is multiplied by $\sqrt{2}$ .
