Question: A certain brokerage house want to estimate the mean daily return on a Certain stock.
A random sample of 19 days yields the following return percentage?
\(2.65,0,18,-1.12,-0.15,-2.98,-1.3,-0.79\),
\(2.75,-1.69,2.1,-2.55,1.24,2.43,0.55,\),
\(0.08,-2.87,-2.11,-2.13,0.8\)
If we assume that the returns are normally distributed, find a \(99 \%\) confidence interval for the mean daily return on this stock.
Then complete the table below
What is the lower limit of the confidence interval? What is the upper limit of the confidence interval?
