Can someone please help me To receive full credit for each problem you must show statistical formula used, process of computation, and provide meaningful interpretations of results in full sentences
• Any table have to be labeled appropriately (e. g., title and column). Columns in a table should
be meaningfully labeled in concise words and with statistical symbols
• Calculations could be rounded up to nearest two decimal points
• Assessment of answers will include producing a neat work, clear interpretation or reasoning,
and statistical correctness
Questions
The following are the test scores of students in a 200-level statistics course:
17, 23, 20, 12, 24, 17, 10, 14, 25, 17, 14, 23, 14, 20, 17, 23, 25, 10, 14, 17, 25, 10, 14, 17, 23, 20, 12, 24, 17, 10, 14, 25, 17, 14, 23, 14, 20, 17, 23, 17
1) Draw a frequency distribution table of ungrouped data and provide necessary columns
and rows of statistical information and symbols (e. g., frequencies, relative frequencies
and percent, cumulative frequencies and percent, total frequencies or N, and total scores
(Xi(f)]. Be sure to provide table title as Table 1 and meaningfully label all the columns
2) What percent of students received the highest score and the lowest score?
3) What percent of students received the most common score?
4) What score did the students receive on average? Show statistical formula and process of
calculation.
5) What score did almost half of the students receive? Show statistical formula and process
of calculation.
6) Draw a grouped frequency distribution table providing necessary statistical information
(e. g., mid-points, frequencies, relative frequencies and percent, cumulative frequencies
and percent, total frequencies or N, and total scores (Mi(]. Explain how you would
make a decision to determine the class size or class limits. Be sure to provide table title as
Table 1 and meaningfully label all the columns
7) Calculate the average or mean from the grouped data. Show statistical formula and
process of calculation. How different is this mean from the average calculated from the
ungrouped data?
8) Draw an appropriate chart/graph (e. g., which one to choose from histogram, pie, or line
chart) to visually show the trends in the test scores.
