Answer 1

Answer:
`13.046< \overline{x}<22.15`

Explanation:

Let x be the random variable that represents the data speed.

Given, Confidence interval for population mean : (13.046, 22.15)

Let
`\overline{x}` be the sample mean.

We need to write the confidence interval in "less than" format.

less than sign → <

Confidence interval in "less than" format will be:

`13.046< \overline{x}<22.15`
