# Thread: methods of inference

1. ## methods of inference

Hey,

not to sure what is meant by "methods of inference".
I have to apply "methods of inference" to the following question but are they not essentially the same.

A. Attempt 60 free throws on your local basketball court, which we will use to answer the following questions:
(I) How accurate are you from the free throw line at basketball?

Average/mean

(II) Is there evidence that you are better at free throws than Ian?
(Ian has a free throw percentage of 80%.)

Null hypothesis

B. Time how long it takes you to sprint the distance between wickets on a cricket pitch (which is 20.12 metres), from a running start. Do this 15 times. We will use these data to answer the following questions:

(I) How long does it take you to run the length of a cricket pitch? (on average)

As above?

(II) Is there evidence that you are faster than David?
(David takes 2.58 seconds to run the length of a cricket pitch.)

Nul hypot again?>

C. Conduct a survey of 40 students, to gauge student views on a topic of your choice.
(I) What proportion of students give the first of the two possible responses to your question?(Where responses are Yes or No)
(II) Is there evidence that the response of students differs from a 50:50 split?

Again as above?

Thank you for your time.

Hey, did you ever get a response to this? I'm doing a similar assignment now and I'm having trouble... Any help would be appreciated!
