Question

Find the distribution of responses about whether there was broken glass at the accident for the subjects in this study using relative frequencies

Answer 1

Probability of having broken glass = 0.1933

Probability of not having broken glass = 0.8067

Explanation:

The Treatment table in the file attached to the given question is written out and completed below;

Treatment

Response Smashed into Hit Control Total

Yes 16 7 6 29

No 34 43 44 121

Total: 50 50 50 150

Using relative frequencies,

the distribution of responses about whether there was broken glass at the accident for the subjects in this study can be computed as follows:

Probability of having broken glass =
`(29)/(150)`

Probability of having broken glass = 0.1933

Probability of not having broken glass =
`(121)/(150 )`

Probability of not having broken glass = 0.8067
