Are you sure this question is correct? It would be a decimal of 34.5 girls
Since the deepest point of Death Valley is below sea level, its altitude is negative. So, the difference between the altitudes is
Subtracting a negative means to add, so we have
Answer:
35) 5/12 36) 7/11
Step-by-step explanation:
Because, when you are drawing a girls name from the hat, the probability would be 7/12, then you replace her name and that would make the probability to draw a boys name 5/12. (since you replaced the girls name before.
now you have a probability of drawing 5/12 for a boys name, and now you don't replace the name, so the probability to draw a girls name out of the hat, would be 7/11
(idk if you have to put both answers on one, so if so, then do that for your answer Example: for 35, if the answer is 5/12, 7/12 then do that
Hope this helped, sorry I am not good at explaining things:)
Answer:
(1238.845 ;1285.376)
Step-by-step explanation:
Conditions for constructing a confidence interval :
Data must be random
Distribution should be normal and independent ;
Based on the conditions above ; data meets initial conditions ;
C. I = sample mean ± margin of error
Given the data :
1241 1210 1267 1314 1211 1299 1246 1280 1291
Mean, xbar = Σx / n = 11359 / 9 = 1262.11
The standard deviation, s = [√Σ(x - xbar)²/n - 1]
Using a calculator ; s = 37.525
The confidence interval :
C.I = xbar ± [Tcritical * s/√n]
Tcritical(0.10 ; df = n - 1 = 9 - 1 = 8)
Tcritical at 90% = 1.860
C. I = 1262.11 ± [1.860 * 37.525/√9]
C.I = 1262.11 ± 23.266
(1238.845 ;1285.376)
± 23.266
The margin of error :
[Tcritical * s/√n]
[1.860 * 37.525/√9]
C.I = ± 23.266
