Answer 1

Answer #1

Part 1
Standard error formula	Standard deviation (number of items )^1/2

Standard error	2 (40 )^1/2
Standard error	0.316227766

Part 2
Margin of error formula	*(Standard deviation)/((number of items )^1/2) Z**
Confidence level	95%
Z value at 95 %	1.96	Value obtained from the confidence table
	=(2/(40^(1/2)))*1.96
Margin of error	0.619806421
