Answer:
The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.
Step-by-step explanation:
We have given,
The sample size n=42
The sample mean 
The population standard deviation 
Let
be the level of significance = 0.05
Using the z-distribution table,
The critical value at 5% level of significance and two tailed z-distribution is

The value of margin of error is




The maximal margin of error associated with a 95% confidence interval for the true population mean is 2.238.
Answer:
3.30012 or 825003/250000
Step-by-step explanation:
0.91667÷5/18
