Answer:
(a) The mean is:
The sum of the values: 1.8 + 5 + 6.3 + 8 + 8 + 4.8 + 2.8 + 4.8 = 41.5
The sum divided by the number of values: 41.5 ÷ 8 = 5.1875
(b) The median is:
The values in numerical order: 1.8, 2.8, 4.8, 4.8, 5, 6.3, 8, 8
The mean of the two middle values: (4.8 + 5) ÷ 2 = 4.9
(c) The mode is:
The values in numerical order: 1.8, 2.8, 4.8, 4.8, 5, 6.3, 8, 8
The values that repeat most often: 4.8, 8 (both appear twice)
Answer:
157.5
Step-by-step explanation:
Answer:
a. The fuel efficiency (mpg) of an automobile is a continuous variable
b. The amount of rainfall at a particular location during the next year is a continuous variable
c. The distance that a person throws a baseball is a continuous variable
d. The number of questions asked during a 1-hr lecture is a discrete variable
e. The tension (in pounds per square inch) at which a tennis racket is strung is a continuous variable
f. The amount of water used by a household during a given month is a continuous variable
g. The number of traffic citations issued by the high- way patrol in a particular county on a given day is a discrete variable
Step-by-step explanation:
<em>Continuous </em>variables assign values in a range of infinitely many values, while <em>discrete</em> variables are countable.
<em>Continuous variables</em> in the above can assume real numbers and there are infinitely many real numbers between any two real numbers.
<em>Discrete variables </em>above can be counted in the given time interval.

Answer:
59/5 or 11.8
Step-by-step explanation:
4(1/5+3)-5(1/5)
4(1/5+3)-5(1/5)
-> 59/5, 11.8
