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

Answer:

Probability of having broken glass =  0.1933

Probability of not having broken glass = 0.8067

Step-by-step 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 = $\dfrac{29}{150}$

Probability of having broken glass =  0.1933

Probability of not having broken glass = $\dfrac{121}{150 }$

Probability of not having broken glass = 0.8067
