Given:
p = 7.6% = 0.076, the percentage of people who stay overnight at the hospital.
E = 1.5% = 0.015, margin of error
95% confidence interval.
The standard error is
Es =

where
n = the sample size.
The margin of error is

where
z* = 1.96 at the 95% confidence level.
Because the margin of error is given, there is no need to calculate it.
The 95% confidence interval is
p +/- E = 0.076 +/- 0.015 = (0.061, 0.091) = (6.1%, 9.1%)
Answer:
The 95% confidence interval is between 6.1% and 9.1%.
Answer:
x=5
Step-by-step explanation:
2x+2-7=5
2x-5=5
2x=10
x=5
D.
Step-by-step explanation:
because cos0 = b/h
so cos0 = 8/15
Okay so you should find the area and then divide it by 45
120*90= 10,800
10,800/45= 240
240 is the amount of packages you will need to cover the floor
