The median for city A is 4 because the bracket is 2, 3.5, 4, 4, 5, 5.5. The middle numbers are 4 which add to eight and divide by two to make 4. The median for city B is 5. 25 because the bracket is 3.5, 4, 5, 5.5, 6, and 6. The middle numbers are 5 and 5.5 which add to 10.5 and divide by two to make 5.25.

Christopher needs to buy wooden boardes to build a box that is 12 inches long, 6 inches wide, and 8 inches high. How many square
anzhelika [568]

Answer:

432 in²

Step-by-step explanation:

To Obtian the square inches of wooden boards required :

Area of box = 2(l * w) + 2(l * h) + 2(h * w)

Length = 12 ; width = 6 ; height = 8

Hence,

Area of box = 2(12 * 6) + 2(12 * 8) + 2(8 * 6)

Area of box = 2(72) + 2(96) + 2(48)

Area of box = 432 in²

In a school district, all sixth grade students take the same standardized test. The superintendant of the school district takes
mixas84 [53]

Answer:

\chi^2 =\frac{25-1}{169} 6.0547^2 =5.206

p_v =P(\chi^2

Since the p value is very low compared with the significance level provided 0.01, we have enough evidence to conclude that the true variance and on this case the deviation is significantly lower than 13 at 1% of significance.

Step-by-step explanation:

We have the following data given

n=25 represent the sample size selected for the test

\alpha=0.01 represent the confidence level  

s^2 =6.0547^2 =36.659 represent the sample variance obtained

\sigma^2_0 =13^2 = 169 represent the value that we want to test

System of hypothesis

We want to review if the population deviation is significantly lower than 13 and we can check this with the variance, the system of hypothesis would be:

Null Hypothesis: \sigma^2 \geq 169

Alternative hypothesis: \sigma^2

Statistic

To test this hypothesis the statistic is:

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

The degrees of freedom for this case are:

df= n-1= 25-1= 24

Replacing in the statistic formula we got:

\chi^2 =\frac{25-1}{169} 6.0547^2 =5.206

P value

since we have a left tailed test the p value would be givne by:

p_v =P(\chi^2

We can find the p value with this excel code:

"=CHISQ.DIST(5.206,24,TRUE)"

Since the p value is very low compared with the significance level provided 0.01, we have enough evidence to conclude that the true variance and on this case the deviation is significantly lower than 13 at 1% of significance.
