Given a sample size n, how will the distribution of the sample mean behave?

Keith_Richards [23]

Answer:
Provided that the sample size, n, is sufficiently large (greater than 30), the distribution of sample means selected from a population will have a normal distribution, according to the Central Limit Theorem.

Explanation:
1. As n increases, the sample mean approaches the population mean
(The Law of Large numbers)
2. The standard error of the sample is
σ/√n
where σ = population standard deviation.
As n increases, the standard error decreases, which means that the error
between the sample and population means decreases.

Jamie recently drove to visit her parents who live 510 miles away. On her way there her average speed was 25 miles per hour fast

tino4ka555 [31]

Answer:

Average speed in mph with which he goes to parent's place = 75 mph

Average speed with he comes back = 50 mph

Explanation:

Distance between Jamie's house and parent's house = 510 miles.

Let u be the average speed in mph with which he goes to their place.

We have the average speed of coming back = (u -25) mph

Total time of journey considering both ways = 17 hours.

Time taken to go their home = 510/u hours

Time taken for coming back = 510/(u-25) hours

So total time = $\frac{510}{u} +\frac{510}{u-25}$

Equating both times we have

$\frac{510}{u} +\frac{510}{u-25}=17\\ \\ 510u-12750+510u=17u^2-425u\\ \\ 17u^2-1445u+12750=0\\ \\ u^2-85u+750=0\\ \\ (u-75)(u-10)=0$

u = 75 mph or u =10 mph

If the average speed in mph with which he goes to their place = 75 mph, average speed with he comes back = 75-25 = 50 mph

If the average speed in mph with which he goes to their place = 75 mph, average speed with he comes back = 10-25 = -15 mph(Not possible)

So, Average speed in mph with which he goes to parent's place = 75 mph

Average speed with he comes back = 50 mph
