Questionnaire for mixture dispenser design

Dear Sir/Madam,
I am a GCSE student that has to design a product to fix a problem. I have chosen to make a mixture dispenser that will help bakers to dispense a uniform amount of mixture. To complete my coursework, I need to include a questionnaire, which has been completed by at least 30 people. 

It will be very helpful and should only take 5 minutes.

Thank You for completing this questionnaire.
