a random sample size of 175 is drawn from a large population. The population standard deviation is 13.6. The sample mean is 87.3
. Estimate the size of the population mean, including the margin error.
1 answer:
Answer:
The size of the population mean would be provided as:
mean +/- std/sqrt(sample size)
<=>
87.3 +/- 13.6/sqrt(175)
<=>
87.3 +/- 1.03
=> Option B is correct.
Hope this helps!

Let x equal a number
3x + 5 = 26
3x = 21
x = 7
the number is 7!
Answer:
Step-by-step explanation:
3x+6=-5-2x-6
+2x. +2x
5x+6= -5-6
5x+6= -11
-6. -6
5x= -17
divide by 5
x= -3.4
Step-by-step explanation:
4x2 - 25b2
We can solve it by the squares so
(2x - 5b) (2x + 5b)
2) x2 - 81
The same case is here so
(x - 9) (x + 9)
