Alculates the number of times the sum of the randomly rolled dice equals each possible value from 2 to 12. repeatedly asks the user for the number of times to roll the dice, quitting only when the user-entered number is less than 1. hint: use a while loop that will execute as long as num_rolls is greater than 1. prints a histogram in which the total number of times the dice rolls equals each possible value is displayed by printing a character, such as *, that number of times. the following provides an example:

Which of the following methods could be considered a “best practice” in terms of informing respondents how their answers to an on-line survey about personal information will be protected? respondents are informed that investigators will try to keep their participation confidential; however, confidentiality cannot be assured. respondents are informed that a research assistant will transfer all the research data to a password-protected computer that is not connected to the internet, via a usb flashdrive. the computer is located in a research team member’s office. the investigator uses the informed consent process to explain her institution’s method for guaranteeing absolute confidentiality of research data. the investigator uses the informed consent process to explain how respondent data will be transmitted from the website to his encrypted database without ever recording respondents’ ip addresses, but explains that on the internet confidentiality cannot be absolutely guaranteed.

(hint: you can test that this formula is working by changing the value in cell q2 to 0, but remember to set the value of cell q2 back to 1036 when the testing is complete.)
