elaborate ? @keen oak
Airline punctuality is a crucial element of passenger satisfaction. Using a random sample of 10 passengers whether the average departure delay time can be considered equal to 20 minutes or if it significantly differs from this benchmark. Find potential Type I and Type II errors, and the one-sample t-test is referenced as a standard method for such inference when the population standard deviation is unknown. Test at 95% confidence level and whether there is a statistically significant relationship between departure delays and overall satisfaction.
So this is the question i made for my assignment
I wanna use hypothesis testing and sampling with CLT and Type 1,2 errors with it
And also the T-test
As you see in the question
Here is the sample
my issues is that im taking the alternative H not equal 20 right
so when im initialising the normal by CLT
but the deviation and population is not known
Using chatgpt
I got the standard deviation amd population mean through some calculations
So im not sure what to do now
How to go through this to the end
Id really appreciate this help bro if you can
hold it down lads
Yess
Not equal to 20
so you have the samples right
The 20 i took it as random
This is sample of 10
Abt delay times in minutes
ya so, calculate the sample mean, sample SD. then find t from the t test formula.
you get the critical values of t for 95% CI
yes.
no
the sample mean you have to calc from your sample data
Oh lord im confused
hold on
Aite😭
so, tell me from the ques, what is your goal
So i have a dataset right
Im using it to apply statistics maths topic
From the question
I wanna use sampling and CLT by normal distribution
With the errors of hypothesis testing
Since i have a random sample
I thought i can put T-test with it
Im merging them all together as a research question
Then with my data from spreadsheet
I can use the statistics to answer and analyze the question
so you wanna do a t test to chcek if the delay time is 20 min or not
Yess
And these also😭
Yeah i know
I got it there
