A $90\%$ confidence interval for an unknown population mean $\mu$ has been calculated as $87±12$.

What is the correct interpretation of this confidence interval?

We are $90\%$ confident that the true mean is between $75$ and $99$.

There is a $0.9$ probability that the true mean is between $75$ and $99$.

$90\%$ of all confidence intervals will be between $75$ and $99$.

If we took many samples from this population, $90\%$ of the computed confidence intervals would contain the true mean.

$90\%$ of data from the population is between $75$ and $99$.
