Just I need help ASAP

g100num [7]

Answer:

x≤3 or x>10

Step-by-step explanation:

x≤3 because the dot is a solid dot at 3 and pointing backward toward numbers less than 3.

x>10 because the dot is an open circle pointing toward numbers greater than 10.

statuscvo [17]

Answer:

If we compare the p value and the significance level provided we see that $p_v >\alpha$ so on this case we have enough evidence in order to FAIL reject the null hypothesis at the significance level provided. And that means that the population variance is not significantly higher than 0.0004, so there is no a violation of the specifications.

Step-by-step explanation:

Notation and previous concepts

A chi-square test is "used to test if the variance of a population is equal to a specified value. This test can be either a two-sided test or a one-sided test. The two-sided version tests against the alternative that the true variance is either less than or greater than the specified value"

$n=30$ represent the sample size

$\alpha=0.05$ represent the confidence level

$s^2 =0.0005$ represent the sample variance obtained

$\sigma^2_0 =0.0004$ represent the value that we want to test

Null and alternative hypothesis

On this case we want to check if the population variance specification is violated, so the system of hypothesis would be:

Null Hypothesis: $\sigma^2 \leq 0.0004$

Alternative hypothesis: $\sigma^2 >0.0004$

Calculate the statistic

For this test we can use the following statistic:

$\chi^2 =\frac{n-1}{\sigma^2_0} s^2$

And this statistic is distributed chi square with n-1 degrees of freedom. We have eveything to replace.

$\chi^2 =\frac{30-1}{0.0004} 0.0005 =36.25$

Calculate the p value

In order to calculate the p value we need to have in count the degrees of freedom , on this case 29. And since is a right tailed test the p value would be given by:

$p_v =P(\chi^2 >36.25)=0.1664$

In order to find the p value we can use the following code in excel:

"=1-CHISQ.DIST(36.25,29,TRUE)"

Conclusion

If we compare the p value and the significance level provided we see that $p_v >\alpha$ so on this case we have enough evidence in order to FAIL reject the null hypothesis at the significance level provided. And that means that the population variance is not significantly higher than 0.0004, so there is no a violation of the specifications.
