A quality-conscious disk manufacturer wishes to know the fraction of disks his company makes which are defective. Step 2 of 2: Suppose a sample of 707 floppy disks is drawn. Of these disks, 630 were not defective. Using the data, construct the 95 % confidence interval for the
population proportion of disks which are defective. Round your answers to three decimal places.

answer:

c 60% on edg

y > 1/3x

y < = -x + 4

hope this : )

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
