z crit = 1.96 95% p-hat = 19 or maybe 19/83 and expressed as a percentage n1 = 83 Do you remember how to get p_hat?
p-hat is the 'proportion in your sample.' It may be given as a percentage, a proportion or you will have to figure it out as a fraction (proportion). What is 19/83 as a percentage.
27% for p_hat? Was it in the options as a percentage on that last problem? Post the options and let's see what is up for grabs.
There are 3 answers that must be given to this question. That, or I am reading the wrong question.
you are correct
what are the values of zcrit, pˆ2 , and n2 for a 95% confidence interval Three questions.
I think I got this one with your help thank you :)
Here is what I posted early on. z crit = 1.96 95% p-hat = 19 or maybe 19/83 and expressed as a percentage n1 = 83
yes that is what I got based on your results and you were correct :) thank you
can we do question 18 as well or do you have to go to sleep? because i dont want to keep you awake or anything
How many Stat questions do you have to do tomorrow?
around 30 but dont worry lol I will most like know how to some of them at least
Let me look at number 18. Hold on.
alright thank you and im sorry if im asking much
Crank this out: |dw:1450250092618:dw|
oh wait I think I got it from here that one is sort of similar to one from my example from previous works in the class
and the last one is 14 and them in off to sleep until tomorrow when I hope to see you again
>>oh wait I think I got it from here that one is sort of similar to one from my example from previous works in the class I don't know what this ^^^ means.
there is a section in my lesson that says worked examples and we have to go step by step doing the work and there is one that is almost the exact same problem to that one
d = .66 - .75 = -.09 (-.09 - .05759, -.09 + .05759 ) (-0.14759 , -0.03241)
Did d turn out to be negative in the problem of which you speak?
hold on let me go back to that section and check
but wait what exactly do you mean by D? do you mean the answer intervals?
All of that was supposed to be done in percentages. Read the problem.
plus that one is extra credit it does not count as much as question 14 does
im sorry is that im falling asleep at this point lol
(-0.14759 , -0.03241) (-14.8% , -3.2% ) We are 95% confident that the difference between the mean wait times for Q and Z is between - 14.8 minutes and- 3.2 minutes. That does not make sense to me.
Let's close out for now.
yeah i only need question 14 to finish that lesson can you help me with just this and then i wont bother any more for today please?
