Studdy Solution

STEP 1

Assumptions1. The age groups are represented as intervals. . The class midpoint is the average of the lower and upper limits of each age group.

STEP 2

We calculate the class midpoint for each age group by adding the lower limit to the upper limit and then dividing by2.
Classmidpoint=Lowerlimit+Upperlimit2Class\, midpoint = \frac{{Lower\, limit + Upper\, limit}}{2}

STEP 3

Calculate the class midpoint for the first age group (25-29).
Classmidpoint=25+292Class\, midpoint = \frac{{25 +29}}{2}

STEP 4

Calculate the value.
Classmidpoint=25+292=27Class\, midpoint = \frac{{25 +29}}{2} =27

STEP 5

Repeat the process for the remaining age groups. For the age group30-34Classmidpoint=30+342Class\, midpoint = \frac{{30 +34}}{2}

STEP 6

Calculate the value.
Classmidpoint=30+342=32Class\, midpoint = \frac{{30 +34}}{2} =32Continue this process for all the age groups.

STEP 7

For the age group35-39Classmidpoint=35+392=37Class\, midpoint = \frac{{35 +39}}{2} =37

STEP 8

For the age group40-44Classmidpoint=40+442=42Class\, midpoint = \frac{{40 +44}}{2} =42

STEP 9

For the age group45-49Classmidpoint=45+492=47Class\, midpoint = \frac{{45 +49}}{2} =47

STEP 10

For the age group50-54Classmidpoint=50+542=52Class\, midpoint = \frac{{50 +54}}{2} =52

STEP 11

For the age group55-59Classmidpoint=55+59=57Class\, midpoint = \frac{{55 +59}}{} =57So, the class midpoints for the age groups are27,32,37,42,47,52, and57 respectively.
