Answer:
9 green peppers and 3 red peppers
Step-by-step explanation:
Lupe's chili recipe makes 12 servings and uses green peppers = 12
Therefore, for 1 serving he uses = = 1 green pepper
He uses red peppers for 12 servings = 4
for 1 serving he uses = red pepper
∴ for 9 servings Lupe needs green pepper = 1 × 9 = 9 green peppers
and for 9 servings Lupe needs red pepper = × 9
=
= 3 red peppers
Lupe needs 9 green peppers and 3 red peppers for 9 servings

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:
Answer:
19 - 28/n
n= 7
19 - 28/7
19-4
= 15
