I need some help with the attachment. It contain some problems.

1. The data shown are the number of grams per serving of 30 selected brands of cakes. Construct a frequency distribution and a relative frequency distribution using 5 classes. STEP 1: Find the Range of the data set. The range is the difference between the highest value and the lowest value. The range of the data set is:____ Enter a number.___ 2. The data shown are the number of grams per serving of 30 selected brands of cakes. Construct a frequency distribution and a relative frequency distribution using 5 classes. STEP 2: Find the class width. Since there are 5 classes (given in the question), we have to divide the range (found in question 1) by 5 and either round down or round up our answer to the nearest whole number. The possible class widths are ___ and ___. Enter a number in each case. Enter the smaller number first. 3. The data shown are the number of grams per serving of 30 selected brands of cakes. Construct a frequency distribution and a relative frequency distribution using 5 classes. STEP 3: Find the five classes. One way to find the class limits is: a. Use the lowest value in the data set as the lower limit of the first class b. Add the class width (found in question 2) to the lower limit of the previous class to find the find lower limit of the next class. c. Repeat this process until you have the five class that will accommodate all the values in the data set. d. The upper-class limit of a class is one less than the lower class limit of the next class. Using the process described above, identify all the class. IMPORTANT: YOU MAY NEED TO TRY ALL THE POSSIBLE CLASS WIDTHS FROM QUESTION 2 TO DETERMINE 42-48 51-56 35-41 27-32 28-34 21-27 39-44 49-55 45-50 33-38 4. The data shown are the number of grams per serving of 30 selected brands of cakes. Construct a frequency distribution and a relative frequency distribution using 5 classes. STEP 4: Complete the frequency table below. A.6 B.9 C.5 D.7 E.3 F.30 G.8 H.4 I.10 21 - 27 28 - 34 25 - 41 42 - 48 49 - 55 A 5. The data shown are the number of grams per serving of 30 selected brands of cakes. Construct a frequency distribution and a relative frequency distribution using 5 classes. STEP 5: Complete the relative frequency table below. A.0.57 B.0.17 C.1.00 D.0.23 E.0.30 F.0.27 G.0.10 H.0.20 21 - 27 28 - 34 35 - 41 42 - 48 49 - 55 A
