<h2>The given statement is false.

Explanation:
If the driver has set the phone to "do not disturb" then definitely the notification that he gets through various apps will be kept silent, calls will reach voice mail and we will be notified with missed calls and our screen will be blank when the call is received. But this do not disturb mode does not control the air-conditioning of the car or blocking the driver from changing the radio station.
It is found from a survey that the road accidents are more when the mobile usage of the driver is more. Many drivers though they know about the consequences, they still use mobile phones while driving.
 
        
        
        
Given:
Actual Production 6,000 units @ 1.5 standard hours per unit.
Budgeted hours: 10,000 
Fixed overhead cost per unit is $0.50 per hour.
6000 units * 1.5 std. hrs/unit = 9,000 hours
Actual hours: 9,000 hours * $0.50 per hour = $4,500
Budgeted hours: 10,000 hours * $0.50 per hour = $5,000
Fixed Factory Overhead Volume Variance = $5,000 - $4,500 = $500 UNFAVORABLE. 
It is unfavorable because the production is inefficient. It is more favorable if the produced units are higher than 6,000 units and the actual hours of production are more than the budgeted hours of production.
