a. Using the class width of 10 give the upper and lower limit for five classes, starting with lower limit of 95 for the first class b. Construct a frequency distribution for the data

Data was collected for 225 fish from the North Atlantic. The length of the fish (in cm) is summarized in the histogram below. 40 35 30 25 20 15 10 15 30 45 60 75 90 105 120 length of fish (cm) Based on the Histogram above, reconstruct the corresponding Frequency Distribution Table Class Frequency Áuənbəs

The following are the grades received on an paper by 25 students.                                          97   97 98    40   45 77    65 65    65   68   81   93   68   71   87   85    88    76   79   78   87   81    81   83   89  a) Fill in the frequency table below using the data given. Use 10-point bins. Note: You may have rows left over.                      Grade Frequency Relative Frequency Cumulative Frequency                                                                         Total:           b) Draw a histogram based on the frequency table in part a . Don’t forget to label properly the axes, and put a title.

A chemical technician measured the temperatures (in C) of 18 different solutions. The temperatures are shown below. Complete the grouped relative frequency distribution for the data. (Note that we are using a class width of 6.) Write each relative frequency as a decimal rounded to the nearest hundredth, not as a percentage.

Construct a frequency distribution for the given data set using 6 classes. In the table, include the midpoints, relative frequencies, and cumulative frequencies. Which class has the greatest frequency and which has the least frequency?
