Answer:
c Yes, because 5/4 > 1
Step-by-step explanation:
5/4 × 6 > 6
5/4
= 1 1/4
5/4 is greater than 1
5/4 > 1
5/4 × 6
= 30/4
= 15/2
= 7 1/2
a No, because 5/4 < 1
b No, because 5/4 < 6
c Yes, because 5/4 > 1
d Yes, because 5/4 > 6
Therefore,
5/4 × 6 > 6 is true
Answer: If p=0.19, then to update this study, the files of 98 public accountants should be studied.
If no prior estimate of the population proportion is given then to update this study, the files of 271 public accountants should be studied.
Step-by-step explanation:
As per given , we have
Margin of error : E = 0.05
Critical value for 90% confidence :
Prior estimate of population proportion: p= 0.19
Formula for sample size :
∴ To update this study, the files of 167 public accountants should be studied.
If no prior estimate of the population proportion is given , then
we take p= 0.05
Required sample size :
∴ To update this study, the files of 271 public accountants should be studied.
