Well, since we have not actually done this experiment, we cannot use a experimental probabiltity, so we can say the correct answer is:

When an experiment was conducted and the results are from an actual experiment or actual data set, it is experimental probability.
When the probability is based on what is SHOULD be, as in flipping a coin should be 50% heads and 50% tails, it is theoretical probability.
One-half represents 50%. This is data from an actual club so I would say it is experimental, LETTER A.

Eva8 [605]

Answer:

a) Z-score = 0.75

b) Z-score = -32.833

Step-by-step explanation:

Step(i):-

Given that mean of the Population = 33

Given a standard deviation of the Population = 12

Let 'X' be a random variable in a normal distribution

Let 'X' = 42

Step(ii):-

$Z = \frac{x-mean}{S.D}$

$Z = \frac{42-33}{12} = 0.75$

Step(iii):-

Given that mean of the Population = 89

Given a standard deviation of the Population = 1

Let 'X' be a random variable in a normal distribution

Let 'X⁻ = 82

$Z = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }$

$Z = \frac{82-89}{\frac{1}{\sqrt{22} } } = -32.833$

Z-score = -32.833
