The variance in a production process is an important measureof the quality of the process. a large variance often signals anopportunity for improvement in the process by finding ways toreduce the process variance. conduct a statistical test todetermine whether there is a significant difference between thevariances in the bag weights for the two machines. use a .05 levelof significance. what is your conclusion? which machine,if either,provides the greater opportunity for quality improvements? machine1 2.95 3.45 3.50 3.75 3.48 3.26 3.33 3.20 3.16

$F=\frac{s^2_1}{s^2_2}=\frac{0.2211^2}{0.0768^2}=8.28$

$p_v =2*P(F_{24,21}8.28)=7.22x10^{-6}$

Since the $p_v < \alpha$ we have enough evidence to reject the null hypothesis. And we can say that we have enough evidence to conclude that the variation between the two machines is significant at 5% of significance.

Step-by-step explanation:

Data given and notation

Machine 1: 2.95 3.45 3.50 3.75 3.48 3.26 3.33 3.20 3.16 3.20 3.22 3.38 3.90 3.36 3.25 3.28 3.20 3.22 2.98 3.45 3.70 3.34 3.18 3.35 3.12

Machine 2: 3.22 3.30 3.34 3.28 3.29 3.25 3.30 3.27 3.38 3.34 3.35 3.19 3.35 3.05 3.36 3.28 3.30 3.28 3.30 3.20 3.16 3.33

n_1 = 23 represent the sampe size for machine 1

n_2 =22 represent the sample size for machine 2

$\bar X_1 =3.33$ represent the sample mean for machine 1

$\bar X_2 =3.28$ represent the sample mean for machine 2

s_1 = 0.2211 represent the sample deviation for machine 1

s^2_1 = 0.049 represent the sample variance for machine 1

s_2 = 0.0768 represent the sample deviation for machine 2

s^2_2 = 0.00690 represent the sample variance for machine 2

$\alpha=0.05$ represent the significance level provided

Confidence =0.95 or 95%

F test is a statistical test that uses a F Statistic to compare two population variances, with the sample deviations s1 and s2. The F statistic is always positive number since the variance it's always higher than 0. The statistic is given by:

$F=\frac{s^2_1}{s^2_2}$

Solution to the problem

System of hypothesis

We want to determine whether there is a significant difference between thevariances in the bag weights for the two machines , so the system of hypothesis are:

H0: $\sigma^2_1 = \sigma^2_2$

H1: $\sigma^2_1 \neq \sigma^2_2$

Calculate the statistic

Now we can calculate the statistic like this:

$F=\frac{s^2_1}{s^2_2}=\frac{0.2211^2}{0.0768^2}=8.28$

Now we can calculate the p value but first we need to calculate the degrees of freedom for the statistic. For the numerator we have n_1 -1 =25-1=24 and for the denominator we have n_2 -1 =22-1=21 and the F statistic have 24 degrees of freedom for the numerator and 21 for the denominator. And the P value is given by:

P value

$p_v =2*P(F_{24,21}8.28)=7.22x10^{-6}$

And we can use the following excel code to find the p value:"=2*(1-F.DIST(8.2838,24,21,TRUE))"

Conclusion

Since the $p_v < \alpha$ we have enough evidence to reject the null hypothesis. And we can say that we have enough evidence to conclude that the variation between the two machines is significant at 5% of significance.

0.128 ; 0.872 ; 0.748 ; 0.124 ; 0.252

Step-by-step explanation:

Given the data above ;

The frequency distribution generated for the number of defects observed on each of 250 lcd screens are as follows :

__number of defects___frequency

0 24

1 82

2 38

3 43

4 31

5 26

6 6

A.) . What proportion of the screens have more than 4 defects? Give your answer to three decimal places.

More than 4 defects = (number of 5 defects + 6 defects) / total number of defects)

(26 + 6) / 250 = 32 / 250 = 0.128

b. What propotion of the screens have at most 4 defects? Give your answer to three decimal places.

Number of (0 + 1 + 2 + 3 + 4) defects

= (24 + 82 + 38 + 43 + 31) / 250

= 218 / 250 = 0.872

c. What proportion of the screens have fewer than 4 defects? Give your answer to three decimal places.

Number of (0 + 1 + 2 + 3) defects

= (24 + 82 + 38 + 43) / 250

= 187 / 250 = 0.748

d. What proportion of the screens have exactly 4 defects? Give your answer to three decimal places.

Number of 4 defects = 31

= 31 / 250

= 0.124

e. What proportion of the screens have at least 4 defects? Give your answer to three decimal places.

Number of (4 + 5 + 6) defects

= (31 + 26 + 6) / 250

= 63 / 250

= 0.252
