I NEED HELP WITH THIS

Answer 1

Explanation:

a) 147

b)147

c) 152

d)65

Answer 2

a) mean = 147

b) median = 147

c) mode = 152

d) range = 65

Explanation:

firsly let’s arrange the numbers of the set in ascending order:

117 , 119 , 138 , 142 , 152 , 152 , 174 , 182

a)

`Mean = (117+119+138+142+152+152+174+182)/(8) =(1176)/(8) =147`

b) the median is the average of the two middle numbers :

`117,119,138, \frac{142,152}{} , 152,174,182`

`median=(142+152)/(2)= 147`

c) the modal height is 152 because 152 is the value that appears most frequently (2 times) in our set

d) the range of a set is the difference between the highest and lowest numbers :

Then

the range = 182-117 = 65
