Answer:

Option B.

Step-by-step explanation:

The given table is

                          Meat              Not meat         Total

Seafood               16                      31                  47

Not seafood        20                      5                  25

Total                     36                    36                  72

From the given table it is clear that:

Seafood-Meat = 16

Not seafood-Meat = 20

Seafood-not meat = 31

Not seafood- not meat = 5

Total = 72

We need to find the joint relative frequency for mall visitors who like seafood and meat.

Joint relative frequency =\dfrac{\text{who like seafood and meat}}{\text{Total}}

Joint relative frequency =\dfrac{16}{72}

Therefore, the correct option is B.

A screening test for a disease shows a positive result in 91% of all cases when the disease is actually present and in 7% of all
Jobisdone [24]

Answer:

0.0713 = 7.13% probability that the result is positive.

Step-by-step explanation:

Probability of a positive test:

91% of 1/650(has the disease).

7% of 1 - 1/650 = 649/650(does not have the disease). So

p = 0.91\frac{1}{650} + 0.07\frac{649}{650} = \frac{0.91 + 0.07*649}{650} = 0.0713

0.0713 = 7.13% probability that the result is positive.
