Answer:
$3822
Step-by-step explanation:
We are given that Each dimension of a rectangular family room is 3.5 times larger than the rectangular bedroom.
So, length of a rectangular family room must be 3.5 times larger than rectangular bedroom.
And Breadth of a rectangular family room must be 3.5 times larger than rectangular bedroom.
So, area of rectangular family room must be larger than rectangular bedroom by times
So, Area of rectangular family room must be 12.25 times larger than rectangular bedroom
Now cost of carpet for bedroom = $312
So, cost of same carpet for family room =
=
Hence the cost to carpet the family room is $3822.

Step-by-step explanation:
Given the initial ratio of 3 parts water to 5 parts fruit juice, you can set up a proportion (equivalent ratios) to determine the amount of water needed with just 1 part of fruit juice:
cross multiply: 5x = 3
divide: 5x/5 = 3/5 or x = 3/5
3/5 = 0.6 parts water
Answer:
Since we FAIL to reject the null hypothesis, then if we construct an interval of 95% of confidence, the 0 should be included, because on the test hypothesis we conclude that there would be no significant difference between the means of the two groups analyzed, and the results obtained on the hypothesis test needs to be consistent with the confidence interval.
Step-by-step explanation:
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
represent the sample mean of calories for the meat hot dogs
represent the sample mean of calories for the beef hot dogs
The system of hypothesis on this case would be:
Null hypothesis:
Alternative hypothesis:
On this case we have the p value obtained, after calculate the statistic and we got that if we select a 5% significance level
we see that
and on this case we can FAIL to rejec the null hypothesis, so there is not a significant difference between the mean of the two tpes of hot dogs analyzed at 5% of significance.
And since we FAIL to reject the null hypothesis, then if we construct an interval of 95% of confidence, the 0 should be included, because on the test hypothesis we conclude that there would be no significant difference between the means of the two groups analyzed, and the results obtained on the hypothesis test needs to be consistent with the confidence interval.
