N a survey of twelve Harbor Business School graduates, the mean starting salary was $93,000, with a standard deviation of $17,00

scZoUnD [109]

Answer: The confidence interval would be (82198.71, 103801.28).

Explanation:

Since we have given that

Mean = $93,000

Standard deviation = $17,000

n = 12 < 30

So, we will use 't-test' to find the 95% confidence interval,

Here , $\alpha =1-0.095=0.05$

and $n-1=12-1=11$

So, according to t table, we get that

$t_{n-1,\frac{\alpha }{2}}=2.200985$

So, interval would be

$\bar{x}\pm t_{n-1,\frac{\alpha {2}}\dfrac{\sigma}{\sqrt{n}}\\\\=93000\pm 2.200985\times \dfrac{17000}{\sqrt{12}}\\\\=93000\pm 10801.2839\\\\=(93000-10801.2839,93000+10801.2839)\\\\=(82198.71,103801.28)$

Hence, the confidence interval would be (82198.71, 103801.28).

Why do we have two words for a big city: metropolis and megalopolis?

liraira [26]

A metropolis is one city with a populace of a half of a million or more inhabitants that sits at the center of an "agglomeration" of littler urban entities that converge into a persistent developed zone. While a megalopolis is a provincial, spread out combination of different open spaces, towns and urban communities.
