Five hundred draws are made at random with replacement from a box of numbered tickets; 276 are positive. Someone tells you that 50% of the tickets in the box show positive numbers. Do you believe it

No

Step-by-step explanation:

Based on the information given in the question, I don't believe that 50% of the tickets in the box show positive numbers.

Since 500 draws are made and 276 are positive, the percentage of the tickets that'll show positive numbers will be:

= 276/500 × 100

= 55.2%

Therefore, about 55.2% of the tickets are positive. The statement that 50% are positive is incorrect.

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

two data sets with the same median will not have the same varaibility
