Answer:
1. 4.5 (9/2)
2. 5.2 (square root of 27)
3. 5.8
4. 6.3 (2pi)
Step-by-step explanation:
The square root of 27 is 5.2, 2pi is 6.3, and 9/2 is 4.5. So the first one is 4.5. The second one is 5.2. The third one is 5.8 and the fourth one is 6.3. I hope this helps! Please mark me brainliest!
6 under par is written as -6
2 over par is written as 2
even par is written as 0
even par is written as 0
Total score: add all the numbers together:
-6 + 2 + 0 + 0 = -4 ( 4 under par).
Answer:
a)
b)
c)
Step-by-step explanation:
Assuming the following question: Because of staffing decisions, managers of the Gibson-Marimont Hotel are interested in the variability in the number of rooms occupied per day during a particular season of the year. A sample of 20 days of operation shows a sample mean of 290 rooms occupied per day and a sample standard deviation of 30 rooms
Part a
For this case the best point of estimate for the population variance would be:
Part b
The confidence interval for the population variance is given by the following formula:
The degrees of freedom are given by:
Since the Confidence is 0.90 or 90%, the significance and , the critical values for this case are:
And replacing into the formula for the interval we got:
Part c
Now we just take square root on both sides of the interval and we got:
It depends on the function
