Answer 1

from the data set ,

minimum value = 133300

the maximum value = 452000

number of observations (n) = 25

according to the 2^k rule,

, k = number of classes.

here,

so, k = number of classes = 5

the class interval that would be the most appropriate is:-

2).number of observations (n) = 25

according to the 2^k rule,

, k = number of classes.

here,

so, k = number of classes = 5

number of classes would be included in a histogram of this data :-
