Answer:
Option D
Step-by-step explanation:
A type I error occurs when you reject the null hypothesis when it is actually true.
The null hypothesis in this case is minimum breaking strength is less than or equal to 0.5.
A type one error would be allowing the production process to continue when the true breaking strength is below specifications.
Answer:
i think its the 3rd one.....
Answer:
I need to know how many students there are to answer this question
Answer:
a) P(12≤χ²≤24)=0.690
b) k=35.85
c) Median=18.34
Step-by-step explanation:
<em>The question is incomplete: "Use the calculator provided to solve the following problems. Suppose that χ² follows a chi-square distribution with 19 degrees of freedom. Compute P(12≤χ²≤24) . Round your answer to at least three decimal places.</em>
<em>Suppose again that χ² follows a chi-square distribution with 19 degrees of freedom. Find k such that P(χ²>k)=0.025. Round your answer to at least two decimal places.</em>
<em>Find the median of the chi-square distribution with 19 degrees of freedom. Round your answer to at least two decimal places."</em>
Compute P(12≤χ²≤24)
Find k such that P(χ²>k)=0.025
The median of the chi-square is:
