These data are the number of junk e-mails Lena received for 9 consecutive days. $\begin{array}{lllllllll}61 & 1 & 1 & 4 & 2 & 30 & 22 & 5 & 9\end{array}$ Send data to Excel Find the range, variance, and standard deviation. Round the variance to one decimal place and the standard deviation to two decimal places, if necessary. Part: $\mathbf{0} / \mathbf{3}$ Part 1 of 3 The range is e-mails.

Step 1 ：These data represent the number of junk e-mails Lena received for 9 consecutive days: 61, 1, 1, 4, 2, 30, 22, 5, 9.

Step 2 ：The range of a set of data is the difference between the highest and lowest values in the set.

Step 3 ：To find the range, subtract the smallest number from the largest number in the dataset.

Step 4 ：The range of the data is calculated as follows: \(61 - 1 = 60\).

Step 5 ：Final Answer: The range of the number of junk emails Lena received for 9 consecutive days is \(\boxed{60}\).
