Answer:
The probability that the sample proportion will differ from the population proportion by greater than 0.03 is 0.0143.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes <em>n</em> ≥ 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
The standard deviation of this sampling distribution of sample proportion is:
The sample selected consists of <em>n</em> = 254 individuals. The sample is quite large, i.e. <em>n</em> = 254 > 30. So the central limit theorem can be applied to approximate the distribution of sample proportion of people in the city that will purchase the products of Goofy's fast food.
The mean is:
And the standard deviation is:
Now, we need to compute the probability that the sample proportion will differ from the population proportion by greater than 0.03.
That is:
Compute the value of as follows:
*Use a <em>z</em>-tale for the probability.
Thus, the probability that the sample proportion will differ from the population proportion by greater than 0.03 is 0.0143.
