Complete Question
The following is a set of hypotheses, some information from one or more samples, and a standard error from a randomization distribution. Test
vs
when the sample has n 900 , and
with
. Find the value of the standardized z -test statistic. Round your answer to two decimal places.
Answer:
The value is ![z = -6.40](https://tex.z-dn.net/?f=z%20%3D%20%20-6.40)
Step-by-step explanation:
Generally the standardized test statistics is mathematically represented as
![z = \frac{\^ p - p }{ SE }](https://tex.z-dn.net/?f=z%20%3D%20%20%5Cfrac%7B%5C%5E%20p%20%20-%20%20p%20%7D%7B%20SE%20%7D)
=> ![z = \frac{0.216 - 0.28 }{ 0.01 }](https://tex.z-dn.net/?f=z%20%3D%20%20%5Cfrac%7B0.216%20%20-%20%200.28%20%7D%7B%200.01%20%20%7D)
=> ![z = \frac{0.216 - 0.28 }{ 0.01 }](https://tex.z-dn.net/?f=z%20%3D%20%20%5Cfrac%7B0.216%20%20-%20%200.28%20%7D%7B%200.01%20%20%7D)
=> ![z = -6.40](https://tex.z-dn.net/?f=z%20%3D%20%20-6.40)
Answer:
Mean = 62
Step-by-step explanation:
X = mean ± sd
82 = mean + 2(s.d) - - (1)
32 = mean - 3sd ___(2)
82 = mean + 2sd
82 - 32= 2sd + 3sd
50 = 5sd
sd = 50/5
sd = 10
From (2):
32 = mean - 3sd
32 = mean - 3(10)
32 = mean - 30
32 + 30 = mean
62 = mean

Step-by-step explanation:
I'm not sure if this is the answer but that's what I got
Answer:
slope is -1
Step-by-step explanation:
y1-y2/ x1-x2
= -3 - 7 / 8 - (-2)
= -10/ 10
= -1
