Hello, can you please help me out with this?

pose you have 35 observations, the smallest and largest of which are 128.2 and 310.4, respectively. Apply the accompanying procedure to choose classes for cutpoint grouping. Use eight classes. Choose the class width by rounding the calculated proximate class width up to the nearest multiple of 5. Choose the lower cutpoint of the first class by rounding the minimum observation down to the nearest multiple of 5. Click the icon to view the procedure for choosing classes. Classes for cutpoint grouping ~ -under -under -under -under -under -under -under -under i Choosing the Classes - X (Use ascending order.) One way that we can choose the classes to be used for grouping a quantitative data set is to first decide on the (approximate) number of classes. From that decision, we can then determine a class width and, subsequently, the classes themselves. Several methods can be used to decide on the number of classes. One method is to use the guidelines below, based on the number of observations. Number of Number of observations classes 25 or fewer 5 6 25 50 7-14 Over 50 15-20 With the preceding guidelines in mind, use the step-by-step procedure below for choosing the classes. Step 1 Decide on the (approximate) number of classes. Step 2 Calculate an approximate class width using the value below and use the result to decide on a convenient class width. er your answer in the edit fields and then click Check Answer.
