Answer 1

To find the number of observations with x1 values greater than 30, count how many x1 values are greater than 30 in the data set.

Step-by-step explanation:

To find the number of observations with x1 values greater than 30, you need to look at the data set and count how many x1 values are greater than 30. You can do this by going through each observation and comparing the x1 value to 30. If the x1 value is greater than 30, you increment a counter by 1. At the end, the value of the counter will give you the number of observations with x1 values greater than 30.
