Answer 1

Answer:

45-53+744(6667)234-7.&5&

Answer 2

Explanation:

The modal group is 40−50.

Estimated Mode = L+((fm−fm−1)+(fm−fm+1)fm−fm−1)×w

where:

L is the lower class boundary of the modal group

fm−1 is the frequency of the group before the modal group

fm is the frequency of the modal group

fm+1 is the frequency of the group after the modal group

w is the group width

Estimated Mode = L+((fm−fm−1)+(fm−fm+1)fm−fm−1)×w

Mode = 40+((156−80)+(156−98)156−80)×10

Mode = 40+(13476)×10

Mode =45.67
