Hugo polled 100 randomly selected people to see if they had exercised that week and found that 85% said they had. lily asked 400 randomly selected people the same question and found that 85% of them also responded that they had exercised that week. if hugo and lily use a 99% confidence level (z*score of 2.58), which statement is true? e = z* - hugo’s margin of error will be exactly 2 times as large as lily’s margin of error. - lily’s margin of error will be exactly 2 times as large as hugo’s margin of error. - hugo’s margin of error will be exactly 4 times as large as lily’s margin of error. - lily’s margin of error will be exactly 4 times as large as hugo’s margin of error.

Hugo polled 100 randomly selected people to see if they had exercised that week and found that 85% said they had. Lily asked 400 randomly selected people the same question and found that 85% of them also responded that they had exercised that week. If Hugo and Lily use a 99% confidence level, then the true statement will be

Hugo's margin of error will be exactly 2 times as large as Lily's margin of error.

The true statement is : Hugo’s margin of error will be exactly 2 times as large as Lily’s margin of error.

Step-by-step explanation:

And value of sigma is same as the response in both the cases is 85%

Hugo's margin of error : n = 100

Lilly's margin of error : n = 400

Hence, the correct statement is : Hugo’s margin of error will be exactly 2 times as large as Lily’s margin of error.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
