Question

find T28 and S48 for the following series
30, 33,69, 39.........​

Answer 1

Answer:

Box plots (also called box-and-whisker plots or box-whisker plots) give a good graphical image of the concentration of the data. They also show how far the extreme values are from most of the data. A box plot is constructed from five values: the minimum value, the first quartile, the median, the third quartile, and the maximum value. We use these values to compare how close other data values are to them.

Answer 2

Answer:

111,4824

Step-by-step explanation:

a=30

d=33-30= 3

n=28

T28= a+27d= 30+81= 111

...................................................

n=48

Sn= (n/2)[2a+(n-1)d]= (48/2)[60+(47)3]

S48= 24×(60+141)= 24×201

=>S48= 4824
