For this case, the first thing we must observe is that the base of the prism is a triangle.
The area of the triangle is given by:
Where,
b: base of the triangle
h: height of the triangle
Substituting values we have:

<h2>Answer with explanation:</h2>
Let p be the proportion of the correct answers.
As per given , we have
, since the alternative hypothesis is right tailed , so the test is a one -tailed test.
If the student gets 52 answers correct out of 80.
i.e. the proportion of correct answers :
Test statistic :
P-value : [ by using p-value table for z (right-tailed)]
Since the p-value(0.0037) is less than the significance level (0.05), so we reject the null hypothesis.
Results : We have enough evidence to support the claim that a student knows more than half of the answers and is not just guessing.
Answer:
See figure attached and explanation below.
Step-by-step explanation:
For this case we have the following dataset given:
0.74, 0.32, 1.66, 3.59, 4.55, 6.47, 9.99, 0.7, 0.37, 0.76, 1.9, 1.77, 2.42, 1.09, 2.03, 2.69,2.41, 0.54, 8.32, 5.70, 0.75, 1.96, 3.36, 4.06, 12.48
And for this case we can use the followinf R code to create the frequency histogram.
> x<-c(0.74, 0.32, 1.66, 3.59, 4.55, 6.47, 9.99,0.7, 0.37, 0.76, 1.9, 1.77, 2.42, 1.09, 2.03, 2.69,2.41, 0.54, 8.32, 5.70, 0.75, 1.96, 3.36, 4.06,12.48)
> length(x)
[1] 25
> hist(x, prob=TRUE)
And for this case we have the histogram on the figure attached. For the number of classes we use the formula of sturges:
And for this case we have approximately 6 classes. And that's what we can see on the figure attached
As we can see most of the values are on the left so then we have a right skewed to the right and the distribution is assymetrical, with most of the values between 0 and 6
