Answer:

67.1

Step-by-step explanation:

Given That:

Time = 200 minutes = 3.5 hours

Distance = 235 miles

We Know That:

Speed = Distance / Time

SO, Speed = 235 divided by 3.5 = 67.1428571

Round this 3sf = 67.1

Hope this helps.

As the sample size becomes larger, the sampling distribution of the sample mean approaches a _____. a. binomial distribution b.

Answer:

c. normal probability distribution

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes 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 a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$
