Answer:
1.691
Step-by-step explanation:
Standard error of the mean is expressed as SEM = S/√n
S is the population standard deviation
n is the sample size (number of observation)
Given S = 27 and n = 255
SEM = 27/√255
SEM = 27/15.97
SEM = 1.691
Hence the standard error of the mean is 1.691

Answer: 6th month
Step-by-step explanation:
Let the month where the plans cost the same be represented by x.
Plan A charges $99 for the phone plus $25 per month. This can be written as:
= 99 + 25x
Plan B charges $39 for a phone and a $35 per month. This can be written as:
= 39 + 35x
We then equate both equations and this will be:
99 + 25x = 39 + 35x
Collect like terms
99 - 39 = 35x - 25x
60 = 10x
x = 60/10
x = 6
The plan will cost the same in the 6th month.
