Ian wants to promote his band on the internet. Site a offers website hosting for $4.95 per month with a $49.99 startup fee. Site
olya-2409 [2.1K]
 <span>I believe for twelve (12) months. 

Site A: $49.95 plus $59.40(4.95 x 12) equals $109.35 

Site B: $9.95 x 12 equals $119.40 

No, wait that's not right. 

Okay, at 8 months, site A is pretty much at $90 (forget the nickels) and site B is $80 so site B is less. 
At 7 months, site A is $85 and site B is $70 so site B is less. 
At 9 months, site A is $95 and site B is $90 so site B is less. 
At 10 months, site A $100 and site B is $100 

It's got to be around 10 months somewhere. 

Ten months would be $99.45 for site A and $99.50 for site B so B is less. 

Eleven months is $104.40 for A and $109.45 for B so now B is more.</span>

Suppose a simple random sample of size n = 14 is obtained from a population with μ = 61 and σ = 17.
sergejj [24]

Answer:

C. The population must be normally distributed.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For us to apply the central limit theorem with a sample size of 14, the underlying population must be normally distributed.

So the correct answer is:

C. The population must be normally distributed.
