Answer: See explanation
Explanation:
a. n = 100. d = 8. ROO = 5%.
i. Sample rate of deviation will be:
= Number of Deviations / Sample size
= 8/100
= 8%
ii. Upper limit rate of deviation = 14%
iii. Allowance for sampling risk will be:
= Upper Limit Rate of Deviation - Sample rate of devaition
= 14% - 8%
= 6%
b. n = 100. d = 4. ROO = 5%.
i. Sample rate of deviation will be:
= Number of Deviations / Sample size
= 4/100
= 4%
ii. Upper limit rate of deviation = 9%
iii. Allowance for sampling risk will be:
= Upper Limit Rate of Deviation - Sample rate of devaition
= 9% - 4%
= 5%
c. n = 100. d = 8. ROO = 10%.
i. Sample rate of deviation will be:
= Number of Deviations / Sample size
= 8/100
= 8%
ii. Upper limit rate of deviation = 12.7%
iii. Allowance for sampling risk will be:
= Upper Limit Rate of Deviation - Sample rate of devaition
= 12.7% - 8%
= 4.7%
