Frequency Distribution

Consider a class of 30 students. The frequency distribution of their scores on a test is as follows: 10 students scored between 70-79, 8 students scored between 80-89, 6 students scored between 90-99 and 6 students scored between 100-110. What is the percentage frequency of students who scored between 80 and 110?

Identify the lower class limits, upper class limits, Blood Platelet Count of class width, class midpoints, and class boundaries for the given frequency distribution. Also identify the number of individuals included in the summary. $\begin{array}{cc}\text { Males (1000 cells/ } \mu \mathrm{L}) & \text { Frequency } \\ 0-99 & 1 \\ 100-199 & 51 \\ 200-299 & 91 \\ 300-399 & 12 \\ 400-499 & 0 \\ 500-599 & 0 \\ 600-699 & 1\end{array}$ Identify the lower class limits (in 1000 cells/ $\mu \mathrm{L}$ ).

A data set has 1000 entries ranging from 1 to 100. The data is to be divided into 10 classes for a frequency distribution table. What is the class width?

Given the frequency distribution table with intervals: 1-10, 11-20, 21-30, 31-40, 41-50 and corresponding frequencies of: 5, 15, 20, 7, 3. What are the midpoints of each interval, and what is the midpoint of the frequency distribution table?

Consider a frequency table with the following data: Scores of 1, 2, 3, 4, 5 with frequencies of 5, 10, 15, 20, 25 respectively. Find the mean of the frequency table.

A frequency table is given as follows: (1, 5), (2, 6), (3, 8), (4, 3), (5, 2). The first element in each pair represents a value, and the second element represents the frequency of that value. What is the variance of the frequency table?

A frequency table is given as follows: \[\begin{array}{|c|c|} \hline X & 1 & 2 & 3 & 4 & 5 \\ \hline f & 4 & 2 & 3 & 1 & 5 \\ \hline \end{array}\] Where X represents the data values and f is their corresponding frequency. Find the standard deviation of the given frequency distribution.

The following frequency table shows the number of players on the Pouncing Tigers soccer team that have scored during each match this year. \begin{tabular}{|cc|} Number of scoring players & Number of matches \\ \hline 0 & 1 \\ \hline 1 & 2 \\ \hline 2 & 4 \\ \hline 3 & 0 \\ \hline 4 & 1 \\ \hline \end{tabular} How many matches have there been this year? matches

Save K Use the given minimum and maximum data entries, and the number of classes, to find the class width, the lower class limits, and the upper class limits. zorrect: 0 \[ \text { minimum }=18 \text {, } \text { maximum }=140,8 \text { classes } \] The class width is 16 . (Type a whole number.) Choose the correct lower class limits below. A. $33,49,66,81,97,113,130,145$ B. $18,33,50,65,81,98,113,130$ C. $34,49,66,82,98,113,129,145$ D. $18,34,50,66,82,98,114,130$ View an example Get more help - Clear all Check answer
