Answer:
y=x-5
Step-by-step explanation:
the slope is one
So to find the y intersect you need to plug in the numbers given, like this:
-2=3 + b
subtract the three
-5=b
the y intercept is -5
y=x-5
Using the z-distribution, it is found that the p-value is of 1.
At the null hypothesis, it is tested <u>that the majority is not against the death penalty</u>, that is:

At the alternative hypothesis, it is <u>tested that the majority is against the death penalty</u>, that is:

The test statistic is given by:
In which:
is the sample proportion.
- p is the proportion tested at the null hypothesis.
In this problem, the parameters are:
.
Then, the value of the <em>test statistic</em> is:



Using a z-distribution calculator, for a <u>right-tailed test</u>, as we are testing if the proportion is greater than a value, the p-value is of 1.

Answer:
with a mean of zero and standard deviation of 1
Answer:
13.75
Step-by-step explanation:
First you know there are 5 students and 5 teachers, for each student it costs 6.25 and for every teacher it cost 1.50. So 5 teachers x 1.50= 7.5. 5 students x 1.25 =6.25. 7.5 +6.25= 13.75
