In a sample of 15 men, the mean height was 171 cm. In a sample of 30 women, the mean height was 158. What was the mean height for both groups put together? Round your answer to the nearest whole number
Homework Answers
The mean height of both the groups combined is :
= ((15*171)+(30*158))/(15+30)
= 2565 + 4740 / 45
= 162.333333
to nearest number is 162 cms
