A random sample of 130 students is chosen from a population of 4,500 students. The mean IQ in the sample is 120, with a standard
barxatty [35]

Answer:

120-2.614\frac{5}{\sqrt{130}}=118.85    

120+2.614\frac{5}{\sqrt{130}}=121.15    

Step-by-step explanation:

Information given

\bar X= 120 represent the sample mean

\mu population mean (variable of interest)

s=5 represent the sample standard deviation

n=130 represent the sample size  

For this case we can't set a margin of error just with a % since they not specify 1.13% respect to something for this case we can omit this value

Confidence interval

The confidence interval for the mean is given by the following formula:

\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}   (1)

The degrees of freedom are given by:

df=n-1=130-1=129

The Confidence level is 0.99 or 99%, the significance would be \alpha=0.01 and \alpha/2 =0.005, and the critical value would be t_{\alpha/2}=2.614

And replacing we got:

120-2.614\frac{5}{\sqrt{130}}=118.85    

120+2.614\frac{5}{\sqrt{130}}=121.15
