You have determined that in the past three years there 7 of the 14 were hand injuries. Previous projections had indicated that under normal conditions, only four hand injuries were expected and 12 other injuries were expected. The remaining injuries were due to other causes. Calculate the chi-square value and discuss whether there was a significant difference in observed data vs. the expected data. Also discuss how the process of hypothesis testing might prove helpful o = 7 hand injuries and 7 other injuriese = 4 expected hand injuries and 12 other injuries
I am a little unclear on how to obtain the p value given the z value and how to determine the tail tests. Can you go a bit more in depth on that part?
need answer and all the work
PLEASE DONT USE EXCEL
Please show as much work as possible, and please do not skip steps. I really want to learn how to solve this, so if you use a axiom please include it. Problem Statement: One out of every one- thousand people have disease X. A new test for X is available, but it's not very accurate. If you have X, there is an 80% chance the test comes back positive and a 20% chance it comes back negative. If you don't have X, there is a 60% chance the test comes back negative and a 40% chance it comes back positive. Question: You are randomly chosen to be tested for X. Since the test is not very accurate, you areadministered the test 10 times; assume the outcomes of these 10 tests are independent. Sevenout of the 10 tests come back positive. Given these test results, what is the probability youhave X?
I got the right calculations for p(x=0) and p(x=1) but I can’t seem to get 2,3, and 4 even though I’m using the same steps. Can you please show me where I’m making an error. Thank you!
I Need help with answering question 2 and 3. To conclude from the table given, there is a big difference in the hotels in the UK. The reason is that the P-Value is 0.5> so, therefore, we accept the value, therefore it's true that there is a big difference in the hotels in the UK. My question is, is my statement correct or am I wrong? This the information that given to me How likely is it that you would recommend <name hotel> to a friend or colleague on a scale from 0 (not likely) to 10 (most likely) What are the differences between hotels in UK: London, Birmingham, Leeds Thank you!
Please solve for all and show all the work and process, Thank you
