If we took repeated samples, approximately $90%$ of the samples would produce the same confidence interval.b. If we took repeated samples, approximately $90%$ of the confidence intervals calculated from those samples wouldcontain the sample mean.c. If we took repeated samples, approximately $90%$ of the confidence intervals calculated from those samples wouldcontain the true value of the population mean.d. If we took repeated samples, the sample mean would equal the population mean in approximately $90%$ of the samples.

From all we get the answer is (C) which in $90%$ confident .

See the step by step solution

## Step 1: Given

The term $90%$ confident ?

## Step 2: Explanation

When creating a confidence interval for a mean, the term "$90%$confident" refers to the supposedly oberserved confidence intervals that hold the true value.

Part c is the answer: if we took repeated samples, nearly $90%$ of the confidence intervals computed from those samples would contain the population mean's true value.

## Step 3: Result

Part c is the correct . ### Want to see more solutions like these?
