If you measure a quantity four times and the standard deviation is 1.0% of the average, can you be 90% confident that the true value is within 1.2% of the measured average?

Step-by-Step Solution:
Step 1 of 3

Chemistry 4/4/2016 Lecture Notes Chapter 23 – Lipids 3 Roles  Store energy  Part of cell membranes  Chemical messengers Defined by a physical property NOT by structure  Solubility in NONPOLAR organic solvents (e.g. ether)  NOT soluble in water  Why are they not soluble in water Just look at the structure – how many carbons can you count! Do carbon compounds dissolve in water easily NO! Structure and classification  Large hydrocarbon (HC) portions  Several are esters or amides of long straight HC chains (= Fatty Acids = FA’s) – PAGE 722 o Waxes – Simple esters o Triesters of glycerol – triacylglycerols (neutral) and glycerophospholipids (contain charged phosphate groups) – FATS AND OL
