Car Insurance Use the histogram below to answer the following questions.

a)How many students were surveyed?
b)What are the lower and upper class limits of the first and second classes?
c)How many students have an annual car insurance premium in the class with a class mark of $752? d)What is the class mark of the modal class?
the right side starting from top to bottom of the histogram starts at 8 then 7 then 6 then 5 then 4 then 3 then 2 then 1 it also has written on that side number of students on the very bottom is has annual amount dollars starting from left to right 650,701,752,803,854,905,956,1007
there is a graph showing volume of each or the amount of each studen that is on the right side of this histogram.
starting from left to right the first one has the amount of 650 and the level or amount line stops at the students number( that is on the right side of this histogram) 2 the next one starts with the amount of 701 and stops at students number 4 the next is 752 stops at 6 next is 803 stops at 8 the next is 854 stops at 7 the next is 905 stops at 3 then the last one starts at 1007 and stops at 1
the histogram is a L shape with the number of students on the right and the amount on the bottom going from left to right can any one help me with this I do not understand it need help

uhh @bruna thats not what they asked......... nor is it helpful... this isnt a assement i have so i dont know how i can help @Iva :(

Certainly! Let's answer each question step by step:

a) How many students were surveyed?
To determine the number of students surveyed, we need to add up the number of students in each class. Looking at the histogram, we can see that the number of students is indicated on the right side. Starting from the top and going downwards, we have 8, 7, 6, 5, 4, 3, 2, and 1 student for each class. Adding these together gives us:
8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 36
So, there were 36 students surveyed.

b) What are the lower and upper class limits of the first and second classes?
To find the lower and upper class limits, we can use the information provided in the histogram. The class limits refer to the range of values that belong to each class. Looking at the histogram, we can see that the first class corresponds to an annual car insurance premium of $650 to $700, and the second class corresponds to an annual car insurance premium of $701 to $751. Therefore, the lower and upper class limits for the first class are $650 and $700, respectively, and for the second class, they are $701 and $751.

c) How many students have an annual car insurance premium in the class with a class mark of $752?
A class mark refers to the middle value within a class. The class mark for the class with an annual car insurance premium of $752 can be determined by adding the lower and upper class limits and dividing by 2. Using the information provided, the lower class limit is $701 and the upper class limit is $751. Therefore, the class mark can be calculated as:
(701 + 751) / 2 = 726
Now we need to determine the number of students in this class, which is indicated on the right side of the histogram. We can see that 6 students belong to this class.

d) What is the class mark of the modal class?
The modal class refers to the class with the highest frequency (i.e., the tallest bar in the histogram). To find the class mark for the modal class, we need to identify the class with the greatest number of students. In this case, it appears that the class with an annual car insurance premium of $701 to $751 has the highest frequency (7 students). To find the class mark, we again calculate the midpoint using the lower and upper class limits:
(701 + 751) / 2 = 726
So, the class mark of the modal class is $726.

Sure, I can help you with that!

a) To determine the number of students surveyed, you need to add up the number of students in each class. Looking at the histogram, you can see that the first class (650-700) has 2 students, the second class (701-750) has 4 students, the third class (751-800) has 6 students, the fourth class (801-850) has 8 students, the fifth class (851-900) has 7 students, the sixth class (901-950) has 3 students, and the seventh class (951-1000) has 1 student. Adding all of these together, we get a total of 2+4+6+8+7+3+1 = 31 students surveyed.

b) The lower class limit is the smallest value that can belong to a particular class, and the upper class limit is the largest value that can belong to a particular class. In this case, the first class has a lower class limit of 650 and an upper class limit of 700. The second class has a lower class limit of 701 and an upper class limit of 750.

c) To find out how many students have an annual car insurance premium in the class with a class mark of $752, you need to look at the height of the corresponding bar in the histogram. In this case, the bar for the class with a class mark of $752 stops at the 6th student, so there are 6 students who have an annual car insurance premium in that class.

d) The modal class is the class with the highest frequency (the tallest bar in the histogram). To find the class mark of the modal class, you need to identify the class with the highest bar and determine its midpoint. Based on the description you provided, it seems like the class with a class mark of $803 has the highest bar. To find the midpoint, you can add the lower class limit and the upper class limit of that class and divide by 2. So, the class mark of the modal class would be (801 + 850) / 2 = $825.

I hope this helps you understand how to answer the questions using the given histogram!
