Workers at a certain soda drink factory collected data on the volumes (in ounces) of a simple random sample of 17 cans of the so
LiRa [457]

Answer:

a)Null Hypothesis: \sigma^2 \geq 0.0196

Alternative hypothesis: \sigma^2

b) \chi^2 =\frac{17-1}{0.0196} 0.0121 =9.878

c) p_v =P(\chi^2

d)  If we compare the p value we see that is higher than the significance level so then we have enough evidence to FAIL to reject the null hypothesis and we can't say that the true deviation is significantly lower than 0.14

Step-by-step explanation:

Data given

n=17 represent the sample size

\alpha=0.01 represent the confidence level  

s^2 =0.11^2 = 0.0121 represent the sample variance obtained

\sigma^2_0 =0.14^2 = 0.0196 represent the value that we want to test

Part a System of hypothesis

On this case we want to check if the population deviation is lower than 0.14, so the system of hypothesis would be:

Null Hypothesis: \sigma^2 \geq 0.0196

Alternative hypothesis: \sigma^2

Part b: Calculate the statistic  

The statistic is given by:

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

And replacing we got:

\chi^2 =\frac{17-1}{0.0196} 0.0121 =9.878

Part c: Calculate the p value

In order to calculate the p value we need to find first the degrees of freedom , on this case 17-1=16. And since is a left tailed test the p value would be given by:

p_v =P(\chi^2

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

"=CHISQ.DIST(9.878,16,TRUE)"

Part d: Conclusion

If we compare the p value we see that is higher than the significance level so then we have enough evidence to FAIL to reject the null hypothesis and we can't say that the true deviation is significantly lower than 0.14
