4. The Vetrone family members are all Cincinnati Reds baseball fans. They went to five games last season. The cost of each game, including parking, tickets,
and food, is listed below.
$266, $201, $197, $188, $162
Round your answers to the nearest cent.
a. What is the mean cost per game attended?
b. What is the range?
c. What is the variance?
d. What is the standard deviation?
e. If all five members of the Vetrone family went to each
game,
what was the
mean cost per person to attend each game?

A) Mean cost per game= $202.8

B). Range= $104

C). Variance= 1182.96

D).Standard deviation=34.39

E). $1014 per person

Step-by-step explanation:

The data of the cost

= $266, $201, $197, $188, $162

A). Mean cost per game

Mean = (266+201+197+188+162)/5

Mean = 1014/5

Mean = 202.8

Mean cost per game= $202.8

B) range = highest value- Lowest value

Range= 266-162

Range= $104

C) variance= ((266-202.8)²+(201-202.8)²+(197-202.8)²+(188-202.8)²+(162-202.8)²)/5

Variance=(3994.24+3.24+33.64+219.04+1664.64)/5

Variance= 5194.8/5

Variance= 1182.96

D). Standard deviation= √variance

Standard deviation= √1182.96

Standard deviation=34.39

E).Mean cost per person

= Mean *5

= 202.8 *5

= $1014 per person
