Answer: (20.86, 22.52)
Step-by-step explanation:
Formula to find the confidence interval for population mean :-
, where = sample mean.
z*= critical z-value
n= sample size.
= Population standard deviation.
By considering the given question , we have
n= 58
Using z-table, the critical z-value for 95% confidence = z* = 1.96
Then, 95% confidence interval for the amount of time spent on administrative issues will be :
Hence, the 95% confidence interval for the amount of time spent on administrative issues = (20.86, 22.52)

Answer:
1296 orders
Step-by-step explanation:
There is a pattern to his orders.
First, he starts with 6.
Second, he made 36.
Third, he made 216.
From here, the pattern can be identified. And, you can extend it further.
Pattern - x · 6
x = the orders.
6, 36, 216
6 (September) × 6 = 36 (October)
36 × 6 = 216 (November)
216 × 6 = 1296 (December)
