Answer:
The probability that the sample proportion will differ from the population proportion by less than 6% is 0.992.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes n > 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 information provided is:

As the sample size is large, i.e. <em>n</em> = 276 > 30, the Central limit theorem can be used to approximate the sampling distribution of sample proportion.
Compute the value of
as follows:

Thus, the probability that the sample proportion will differ from the population proportion by less than 6% is 0.992.
Answer:
49.1%
Step-by-step explanation:
From the table, the number of male voters who are registered Democrats is given as 600. Moreover, the total number of male voters is given as 1222. Therefore, the probability that a randomly chosen male voter is a registered Democrat will be calculated as;
number of male voters who are registered Democrats / total number of male voters
600/1222 = 0.491
As a percentage this becomes;
0.491 * 100 = 49.1%
