Answer :
The Mean is 43 and Standard Error of x is 0.7225
What is Statistics?
Statistics is the study of data collection, analysis, presentation, and interpretation. Much of the early push for the subject of statistics came from government demands for census data as well as information about a range of economic operations.
Solution:
We are provided with the Sample Size (n) = 16
Mean (μ) = 43
Standard Deviation (σ) = 1.7
We need to find:
Standard Error of x
So, to calculate Standard Error of x we need to find variance first
Variance = (Standard Deviation)^2
Variance = 1.7 * 1.7 = 2.89
Standard Error = Variance / √Sample Size
Standard Error = 2.89 / √16
Standard Error = 2.89 / 4
Standard Error of x is 0.7225
