b. There are not 15 successes and 15 failures. A confidence interval can be computed by adding 2 successes and 2 failures.
c. There are not 15 successes and 15 failures. A confidence interval can be computed by adding 4 successes and 5 failures.
d. There are at least 15 successes and 15 failures. A large sample confidence interval for the population proportion can be computed with no additional value.
She started off with 120 then spent 25.65 on a shirt then 4.58 on a snack 25.65 and 4.58 are the numbers that you have to add together then subtract from 120. so 25.65+4.58=30.28 So then you subtract 30.28 from 120 and get 89.72 She has $89.72 left over Hope I helped :)
