Any of you guys who feeling comfortable with anything of these?
Im really lost :?:
You observe the following sample (rounded) drawn from a normal random variable
X~N(µ,ó²):
22, 19, 14, 15, 20, 20, 21, 14, 19, 18, 15, 14, 15.
a) Use the sample to estimate µ
and ó².
b) Estimate the variance of the sample average ó²?
c) Find a 99% confidence interval for µ
