Answer:
a) 4
b) 3
c) 5
d) 5
e) 2
Step-by-step explanation:
a) 4+4=8, 8+4=12, 12+4=16, 16+4=20
b) 6+3=9, 9+3=12, 12+3=15, 15+3=18
c) 8+5=13, 13+5=18, 18+5=23, 23+5=28
d) -10+5= -5, -5+5=0, 0+5=5, 5+5=10
e) 3+2=5, 5+2=7, 7+2=9, 9+2= 11
Answer:
i did them both, but one of them might be wrong...
Step-by-step explanation:
check and see
The answer is D.
first get 8/(t-2)/6
use rule a/b/c = (ac)/b
6*8 = 48/(t-2)
now you have (4t^2-16)/48/(t-2)
fraction rule again...
=(4t^2-16)(t-2) / 48
now factor 4t^2-16 = 4(t^2-4)
this leaves you with:
4(t-2)(t^2-4)/48
=(t^2 - 4)(t-2) / 12
Answer:
B. The intervals are centered around the sample mean GPA.
D. 95% of the intervals will contain the population mean in the long run.
Step-by-step explanation:
Confidence interval:
Depends on two things: The sample mean and the margin of error.
Lower end: Sample mean - margin of error
Upper end: Sample mean + margin of error
This means that the intervals are centered around the sample mean.
x% level:
x% of the intervals will contain the population mean in the long run.
So the true statements are:
B. The intervals are centered around the sample mean GPA.
D. 95% of the intervals will contain the population mean in the long run.
