Answer:
i dont get whats the question
Step-by-step explanation:
You have to multiply 36 times 4 =144 . So you do this like this (30 times 4) +(4 times 6)= so (120)+(24)= 144. Answer is 144
3(9+5) all over 6
Multiply the number outside the parenthesis with the numbers inside the parenthesis
27+15 all over 6
Add 27 and 15 together.
42/6
Divide 42 by 6.
Final Answer: 7
So you were correct! The answer is 7

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:
*Use a <em>t</em>-table.
The rejection region can be defined as follows:
Reject <em>H</em>₀ if: or .
