Any practices should best be based on a research - this is the correct answer. (a. child development and research) Research is the best source of actual knowledge, rather than people's best guesses (people's best guesses might lead government regulations, but it would be better if they also followed research results.).

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

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