Determine the ratio of the kitten ears to the tails
A kitten has 1 tail and 2 ears.
Assume each individual got 1 kitten each
This implies that,
The ratio of ears to tail is then calculated as follows:
Ratio = Number of ears : Number of tails
This gives
Divide by 13
Answer:
(c) if n is large, then the sampling distribution of the sample mean can be approximated closely by a normal curve.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation
, the sampling distribution of the sample mean, with a large sample size, can be approximated to a normal distribution with mean
and standard deviation
.
This is valid no matter the shape of the population.
So the correct answer is:
(c) if n is large, then the sampling distribution of the sample mean can be approximated closely by a normal curve.
