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
