Find the (a) mean, (b) median, (c) mode, and (d) midrange for the data and then (e) answer the given questions. Listed belo
w are the highest amounts of net worth (in millions of dollars) of all celebrities. What do the results tell us about the population of all celebrities? Based on the nature of the amounts, what can be inferred about their precision?
1 answer:
Answer:
(a)182.5
(b)175
(c)160
(d)220
(e)A .The results tell us that the most common celebrity net worth is the mode,but all other celebrities are expected to have net worths approximately equal to the mean,median or mid-range
(f)A. The values are all whole numbers, so they appear to be accurate to the nearest whole number
Step-by-step explanation:
Taking the attached data to be that for this question then, the amounts are;
280 190 185 180 175 175 160 160 160 160
Then arranging the values in ascending order
160 160 160 160 175 175 180 185 190 280
(a)The mean will be;
Mean=sum of values/number of values
Sum of values= 160+ 160+ 160+ 160+ 175+ 175+ 180+ 185+ 190 +280=1825
Number of values=10
Mean=1825/10 = 182.5
(b) Median is the center value when we arrange the given data in increasing order
160 160 160 160 175 175 180 185 190 280-------------we have two center values
So, to get the median, find the average of the values
=(175+175)/2 = 175
(c) Mode is the value that appear most in the data set
160 appears four times
Mode=160
(d) Mid-range is a type of average where you add the highest value and the lowest value of the data set and divide by 2
Highest value given is =280
Lowest value given is=160
Mid-range= (280+160)÷2 =440/2 =220
(f)From the results given you can see that the common celebrity net worth is the mode,160 that appears four times in the data set.All the other celebrities have net worth approximate to the mean 183, the median 175 or mid-range 220
(g)Precision is the closeness of a set of values to one another.You can see the values are all whole numbers that appear to be recorded to the nearest whole number
