<span>Statistical sampling:
Uses laws of probability for selection and evaluation of a sample.
Allows for quantification of audit risk and sufficiency of audit evidence.
Nonstatistical sampling:
Does not utilize statistical models in calcualtions.
Uses a non-mathematical approach to determine sample sizes and evaluate the selected samples.</span>
I would either use a histogram or a frequency chart, but histogram is easier and neater
Answer:
1.33333333333
Step-by-step explanation:
Answer:
A) Population standard deviation is known.
B) Option 3
H0: μ =520,
H1: μ ≠ 520
z > 1.96 or z < -1.96
Step-by-step explanation:
A) The normal distribution should be used for the sample mean because the population standard deviation is known. Usually, when the standard deviation is unknown we don't use normal distribution except there is an underlying normal approximation.
B) Null Hypothesis:H0: μ =520,
Alternative hypothesis H1: μ ≠ 520
At 5% level of significance, from standard tables, we will reject H0 if;
The test statistic; z > 1.96 or z < -1.96
