Consider the following example, then answer the following questions to explore aspects of the frequency distribution and its spreadsheet functionalities.

The number of patients at Central Valley Hospital who present at its emergency room with symptoms of a highly contagious virus on randomly selected days during an outbreak were as follows:

32 33 33 34 36 37 39 42 43 45 46 47 48 49 49 50 52 53 54 54

For organizationalpurposes, an administrative intern at the hospital sorts the data into five classes:lower thirties, upper thirties, lower forties, upper forties, and lower fifties.

The intern computes the frequency for the second class (upper thirties)to be 3, and its correspondingrelative frequency as 15%.

Do you agree or disagree with the intern?

Agree

Disagree

The intern computes the cumulative frequency for the second class (upper thirties) as7, or 4from the first class plus 3from the second class.

Do you agree or disagree with the intern?

Agree

Disagree

The intern determines the class mark or midpoint for thefirstclass to be what value,reported without insignificant digits, extra punctuation,or characters?

Answer:

The intern determines the class mark or midpoint for thesecondclass to be what value,reported without insignificant digits, extra punctuation,or characters?

Answer:

The intern knows that the class marks or midpoints can be determined by computing the medians or means of the class limits.

Do you agree or disagree with the intern?

Agree

Disagree

The intern also knows that summing up the relative frequencycolumn in a frequency distribution table results in a sum of1or100%, becauseallthe data should have been counted.

Do you agree or disagree with the intern?

Agree

Disagree

The intern interpreted the data to state that 30%of the time the number of patients presenting at the hospital with symptoms of this highly contagious virus is in the upper forties,based on this data collection.

Do you agree or disagree with the intern?

Agree

Disagree

Furthermore,the intern interpreted the data to state that 25%of the time the number of patients presenting at the hospital with symptoms of this highly contagious virus is in the lower fifties,based on this data collection.

Do you agree or disagree with the intern?

Agree

Disagree
