The answer is A when u have a little x u multiply the amoun the number u multiply it the amount of times they give for example 4 with a 5 on top is 4x4x4x4x4 multiply the 4, 5 times
Answer:
slope is -1/12
Step-by-step explanation:
slope =y2 - y1 / x2-x1
Answer:
Reject <em>H</em>₀ if:
or
.
Step-by-step explanation:
The hypothesis for the one-tail t-test is:
<em>H</em>₀: The population mean is 100, i.e. <em>μ</em> = 100.
<em>Hₐ</em>: The population mean is less than 100, i.e. <em>μ</em> < 100.
The significance level of the test is, <em>α</em> = 0.05.
The number of observations in the sample is, <em>n</em> = 25.
The degrees of freedom of the test is:
df = n - 1
= 25 - 1
= 24
Compute the critical value of <em>t</em> as follows:
![t_{\alpha, (n-1)}=t_{0.05, 24}=1.711](https://tex.z-dn.net/?f=t_%7B%5Calpha%2C%20%28n-1%29%7D%3Dt_%7B0.05%2C%2024%7D%3D1.711)
*Use a <em>t</em>-table.
The rejection region can be defined as follows:
Reject <em>H</em>₀ if:
or
.
<span>(12/18) 12r=1
12\18 x 12=8r
8r=1 then divide both sides by 8
r=1\8</span>
