Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 685 randomly selected adults showed that 61% of them would erase all of their personal information online if they could. Find the value of the test statistic.

417 is the number of adults that would erase their personal information online if they could, they are the 61%. The complete number is 417,85, but we have to adjust the answer for people.

Step-by-step explanation:

To find the answer we need to do a Rule of Three. The Rule of Three is a Mathematical Rule that will help us to solve problems based on proportions.

1. I know that a 685 adults were surveyed, so this is the 100%. 61% say they would erase all of their personal information online if they could, and we don't know the numbre of people in here.

2. So 685 adults 100%

            X adults   61%

Here we have to put the same elements in the same columns. Students with studients and percentage with percentage.

3. Now I have to cross these details. I have to multiple 61*685. So:

61*685= 41785

4. Then divide that result by 100.

41785/100= 417,85

5. So 417 is the total number of adults that would .

its d. the first coordintaes are 10,32
