The double number line shows that 444 bottles of water cost 101010 dollars at a music festival. Based on the ratio shown in the
double number line, how much does 333 bottles of water cost?

Answer:
Please see the attachment for double number line.
Explanation:
We are given cost of 4 water bottles is $10
We can write ,
Cost of 4 bottles = $10
Cost of 1 bottle = $2.5
Cost of 2 bottles =$5
Cost of 3 bottles = = $7.5
Cost of n bottles = $2.5n
Now we draw the double number line.
Bottom line(Line 1) will take as number of bottles:
1 2 3 4 5 6
Above line (Line 2) will show the cost of corresponding number of bottles:
2.5 5 7.5 10 12.5 15

Answer:
Option 3 is correct.
The data do not provide sufficient evidence to reject H0; thus, we cannot conclude that the mean point spread of home games is higher than that of away games.
Step-by-step explanation:
Before anything else, we first give the null and alternative hypothesis for this question.
Null hypothesis would be that there isn't significant evidence to conclude that the mean point spread of home games is higher than that of away games.
H0: µ1 = µ2
And the alternative hypothesis would be that there is significant evidence to conclude that the mean point spread of home games is higher than that of away games.
Ha: μ1 > μ2
The data from the output of the analysis of the hypothesis test is missing from the question. It was obtained online and is attached to this solution of the question.
The table consists of the difference, the sample mean, the standard error of the mean, degree of freedom, the test statistic and most importantly, the p-value. It is the p-value that absolutely gives us the concluding statement of the hypothesis testing.
When the significance level for a test isn't provided, the convention is usually to use 5% significance.
Interpretation of p-value
When the (p-value > significance level), we fail to reject the null hypothesis and when the (p-value < significance level), we reject the null hypothesis and accept the alternative hypothesis.
So, for this question, significance level = 0.05
p-value = 0.4351
0.4351 > 0.05
Hence,
p-value > significance level
This means that we fail to reject the null hypothesis & say that 'The data do not provide sufficient evidence to reject H0; thus, we cannot conclude that the mean point spread of home games is higher than that of away games'.
Hope this Helps!!!
