The given data shows that the number of interruptions that occur during each hour of her day ranges from 0 to 3. To calculate the average number of interruptions over the last month, we need to add all the interruptions and divide by the total number of hours. From the given data, we can calculate the average as follows:

Total interruptions = (0*30) + (1*70) + (2*50) + (3*10) = 190
Total hours = 160

Average interruptions per hour = Total interruptions / Total hours = 190 / 160 = 1.1875

Therefore, on average, she should expect 1.2 interruptions per hour, not 1.0 interruptions per hour. Hence, the statement is false.
