The activation temperature (in â¦F) of a sprinkler system, Y , is normally distributed with population mean µ and population variance Ï 2 = 52 . A random sample of n = 10 sprinklers is obtained and the activation temperature is recorded for each sprinkler. The sample mean is Y = 120.
Required:
a. Calculate a 95% confidence interval for µ.
b. What is the standard error of the sample mean?
c. What is the margin of error of the confidence interval in (a)?
