How do i correctly make this hypothesis statement out using confidence intervals? I have "As we observe it is very unlikely to obtain a 5% monthly return in bitcoin with an alpha of 1% it may happen although it is very unlikely (range of L1-20.30% and UL 5.35%). If we move up the alpha to 5% so its not possible as 5% is out of the range (L1-17.25%UL 2.27%). In conclusion it is very unlikely to obtain the 5% monthly return." But I know that isn't right. Here is my data.
