3. In some 4.0 grading systems, a student's grade point average (GPA) is calculated by assigning letter grades the following numerical values.

   	A	=	4.00		B−	=	2.67		D+	=	1.33
   	A−	=	3.67		C+	=	2.33		D	=	1.00
   	B+	=	3.33		C	=	2.00		D−	=	0.67
   	B	=	3.00		C−	=	1.67		F	=	0.00

   Another measure of central tendency for a set of data is called the midrange. The midrange is defined as the value that is halfway between the minimum data value and the maximum data value. That is,

   Midrange = 

   minimum value + maximum value

   2

   .

   The midrange is often stated as the average of a set of data in situations in which there are a large amount of data and the data are constantly changing. Many weather reports state the average daily temperature of a city as the midrange of the temperatures achieved during that day. For instance, if the minimum daily temperature of a city was 60° and the maximum daily temperature was 90°, then the midrange of the temperatures is 

   60° + 90°

   2

    = 75°.

   
   
   Find the midrange of the following daily temperatures,which were recorded at three-hour intervals. (Round your answer to one decimal place.)

   56°, 61°, 58°, 77°, 76°, 75°, 80°, 60°, 78°
