Suppose 56% of the registered voters in a country are republican. if a sample of 447 voters is selected, what is the probability that the sample proportion of republicans will be less than 60%? round your answer to four decimal places.

0.9554

Step-by-step explanation:

Given : The proportion of  the registered voters in a country are Republican = P=0.56

The number of voters = 447

The test statistic for proportion :-

For p= 0.60

Now, the probability that the sample proportion of Republicans will be less than 60% (by using the standard normal distribution table):-

Hence, the probability that the sample proportion of Republicans will be less than 60% = 0.9554

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

it has to have an angle of 90 degrees
