Answer:
The number of needed subjects to estimate the mean HDL= 31
Explanation:
Given that:
. standard deviation, s= 11.6
. Margin of error, ME = 2
s= 11.6
ME = 2
. The 90% margin of error is defined as:
ME = Z₀,₉÷₂ X σ÷√η
coeficient = (0,90/2)
2= 1.645 x 11.6/√η
√η= (1.645 x 11.6)÷ 2
η= √9.541
η= 30.888
η≈31
