<h2>6 π cm</h2><h2>-------------------------------</h2>
<u>Step-by-step explanation:</u>
diameter = 6cm
radius = diameter ÷ 2
= 6 ÷ 2
= 3cm
circumference = 2π × radius
= 2 π × 3cm
= 3π cm

As it says, the second one even it surveys fewer gamers, but their yearly income is verified, which are accurate, unlike the first one, where the gamers only report their income, which is not 100% true. some people may fake the number. therefore, the second one is more accurate and believable.

Answer:
B. It is reasonable to use the? z-interval procedure in this case? since, although the sample is small? (size less than? 15), the variable under consideration is very close to being normally distributed.
Step-by-step explanation:
answer b is considered to be correct because we know that the population is normal and the standard deviation is known, which allows using the interval z, the answer A is not correct because although the option to use the interval z is given, which is correct, the large sample is not favored, the answer C and D are incorrect because they both reject the use of the z interval and in d it is further rejected that although there is a normal distribution the sample is not, which is false
A is poor
B is good
C is marginal
