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

Darya [45]

Answer:

Correct option: (D).

Step-by-step explanation:

A null hypothesis is a hypothesis of no difference. It is symbolized by <em>H₀</em>.

A Type I error is the probability of rejection of the null hypothesis of a test when indeed the the null hypothesis is true.

The type I error is also known as the significance level of the test.

It is symbolized by P (type I error) = <em>α</em>.

In this case the researcher wants to determine whether the absorption rate into the body of a new generic drug (G) is the same as its brand-name counterpart (B) or not.

The hypothesis for this test can be defined as:

<em>H₀</em>: The absorption rate into the body of a new generic drug and its brand-name counterpart is same.

<em>Hₐ</em>: The absorption rate into the body of a new generic drug and its brand-name counterpart is not same.

The type I error will be committed when the null hypothesis is rejected when in fact it is true.

That is, a type I error will be made when the the results conclude that the absorption rate into the body for both the drugs is not same, when in fact the absorption rate is same for both.

Thus, the correct option is (<em>D</em>).

Can i get help on this question<br> x+4= -9 1/4
Bas_tet [7]
Answer:

Please simplify this fraction c:
Liula [17]
F you just want to see the really short way, just skip down to AAAAAAAAAAAA

so, here is the long explanation
exponential properties
x^{-m}= \frac{1}{x^m}

don't forget pemdas
2x^2=2(x^2)

so
\frac{2x^{-4}}{3xy}=\frac{2 \frac{1}{x^4} }{3xy}=  \frac{2}{3x^5y}


AAAAAAAAAAAAAAAAAAAAAAAA
so we see
the original equatio is
\frac{2x^{-4}}{3xy}

remember
\frac{ab}{cd} =( \frac{a}{c})( \frac{b}{d})

so we can seperate the constants
\frac{ab}{cd} =( \frac{2}{3})( \frac{x^{-4}}{xy})

we know that the placeholders cannot affet the position of the constants unless they are grouped together which they are not

terfor the answer must have 2/3 in it

the only one that hsa that is A
