0.016
Step-by-step explanation:
To find the probability we have to Divide the number of events by the total number of possible outcomes. This will result in the probability of the single event.
Therefore, the formula of probability is
In the given case,
Which is our required answer.
Answer:
The sampling distribution is, p = center = 0.043
The standard deviation of the sample, s = 6.0015×10⁻⁴
The shape is normal
Step-by-step explanation:
Here we have the standard deviation of a sample proportion, given by the following relation;
The center = p = 4.3% or 0.043
The shape is found by the value of n×p hence;
114250 × 0.043 = 4912.75 > 10 and
n(1 - p) = 114250 × (1 - 0.043) = 109337.25 also > 10 hence the shape is normal.
