Step-by-step explanation:
B. Yes, we are 99% confident that the population mean is within the interval.
C. Yes, 225 is below the interval minimum, so it is reasonable to conclude the average cholesterol level is greater than 225 mg/dl.
D. No. Increasing the sample size would decrease the margin of error, so the ends of the interval would move closer to the sample mean of 251.9. So the interval minimum would still be higher than 225.
Answer:
3
Step-by-step explanation:
1926/9=214
1923+3=1926
Simplify the ration expression

start by seeing if anything in the numerator or denominator can be factored,
you should notice that you can factor out a 3 from 3x-6 in the numerator
when you do so, the result is

now, since there is an x-2 in the numerator and denominator, they "cancel" out since

however, only when

since

when you cancel out the x-2, you're left with 3
hence, your answer is C
Answer:
The answer to your question is: ( - 24 / 29, ∞ )
Step-by-step explanation:
6x + 3 < 8 (8x + 6) + 3
6x + 3 < 64x + 48 + 3
6x + 3 < 64x + 51
6x - 64x < 51 - 3
- 58 x < 48
x > - 48 / 58
x > - 24 / 29
( - 24 / 29, ∞ )
