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):

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

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

Which value of m satisfies the inequality 170-7m >99?

Shkiper50 [21]

Answer:

$\huge \purple{m < \frac{71}{7} } \\$

Step-by-step explanation:

$170 - 7m > 99$

<u>Move 170 to the right side of the inequality</u>

$- 7m > 99 - 170 \\ - 7m > - 71$

<u>Divide both sides by - 7</u>

$\frac{ - 7m}{ - 7} > \frac{ - 71}{ - 7} \\ m > \frac{71}{7}$

Flip the signs

We have the final answer as

$m < \frac{71}{7} \\$

Hope this helps you
