Answer:
20
Step-by-step explanation:
1800/90 = 20
Answer:
Explained below.
Step-by-step explanation:
(A)
The p-value is well defined as per the probability, [under the null-hypothesis (H₀)], of attaining a result equivalent to or more extreme than what was the truly observed value of the test statistic.
The <em>p</em>-value of the test was, <em>p</em> = 0.3822.
That is the probability that Remedy B has a greater salvage rate than A is 0.3822, given that rates are the same for Remedy A and B.
(B)
The significance level of the test is: α = 0.05.
A small p-value (typically ≤ 0.05) specifies strong evidence against the null hypothesis (H₀), so you discard H₀. A large p-value (> 0.05) specifies fragile proof against the H₀, so you fail to discard H₀.
The p-value of the test is very large. The null hypothesis will not be rejected.
Concluding that salvage rates are the same for Remedy A and B.
(C)
A type II error is a statistical word used within the circumstance of hypothesis testing that defines the error that take place when one is unsuccessful to discard a null hypothesis that is truly false.
In this case a type II error could have been made as the null hypothesis was not rejected.
The type II error could have been made because of the following reasons:
- The sample size selected is too small.
- Significance level of the test must be small.
As the sample selected is quite large, the only potential consequence of this error is that the significance level of the test must be small.
Answer:
1) point slope form: y-y1=m(x-x1) so y-3=5/3(x-1)
y-3=5/3x-5/3
y=5/3x+4/3 <---bc 9/3-5/3=4/3
2)Plug in 1,2,3,4,5 for x and solve
y=5/3*1-4/3
y=1/3 (1, 1/3)
y=5/3*2-4/3
y=2 (2,2)
y=5/3*3-4/3
y=11/3 (3, 11/3)
y=5/3*4-4/3
y=16/3 (4, 16,3)
y=5/3*5-4/3
y=24/3 or 8 (5,8)
3) Plot the ordered pairs I wrote above
The answer is 5. Take 10 and divide that into 2 groups equally.
Answer:
The strategy to evaluate these expressions is called PEMDAS.
Step-by-step explanation:
<h3>Problem #1</h3>
We're going to be following the rule of PEMDAS:
- Parentheses
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
Keep in mind that multiplication/division and addition/subtraction are done from left to right.
In the first expression (written above), we'll first evaluate everything inside the brackets first (brackets are used when there are parentheses inside of it - but they serve the same function). There are parentheses in these brackets, so that will be the absolute first step in evaluating.
Solve for then rewrite the expression.
Now finish evaluating inside the parentheses by dividing 15 by 5.
The last step to evaluate the expression is to subtract 3 from 15.
<h3>Problem #2</h3>
Evaluate everything inside the the brackets. Start with the parentheses since that is first according to PEMDAS. Add 1 and 3 together then rewrite the expression.
Exponents are solved next after parentheses in PEMDAS, so evaluate the exponent.
Multiplication is done before subtraction, so multiply 3 and 16 together.
Finish evaluating inside the brackets by subtracting 48 from 50.
The last step in evaluating the second expression is to multiply 4 and 2 together, which gives us 8.
