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:
D. 22,417 feet
Step-by-step explanation:
Fine the diagram in the attachment for proper elucidation. Using the SOH, CAH, TOA trigonometry identity to solve for the distance (x) from the plane (P) to the observer (O), the longest side x is the hypotenuse and the side facing the angle of elevation is the opposite.
Hypotenuse = x and Opposite = 15,000feet
According to SOH;


Hence the distance (x) from the plane P to the observer O is approximately 22,417 feet
Answer: There are 667 owls for every 1000 squirrels.
Step-by-step explanation:
Since we have given that
Number of owls = 30
Number of squirrels = 45
If the number of owls and squirrels will continue to increase.
If there are 1000 squirrels, then the number of owls would be

Hence, there are 667 owls for every 1000 squirrels.
