A random sample of n = 8 E-glass fiber test specimens of a certain type yielded a sample mean interfacial shear yield stress of
ANTONII [103]

Answer:

32.9-2.365\frac{4.9}{\sqrt{8}}=28.80    

32.9+2.365\frac{4.9}{\sqrt{8}}=37.00    

Step-by-step explanation:

Information given

\bar X=32.9 represent the sample mean for the sample  

\mu population mean (variable of interest)

s=4.9 represent the sample standard deviation

n=8 represent the sample size  

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=8-1=7

Since the Confidence is 0.95 or 95%, the value of \alpha=0.05 and \alpha/2 =0.025, and the critical value for this cae would be t_{\alpha/2}=2.365

Now we have everything in order to replace into formula (1):

32.9-2.365\frac{4.9}{\sqrt{8}}=28.80    

32.9+2.365\frac{4.9}{\sqrt{8}}=37.00
