Aresearcher studying public opinion of proposed social security changes obtains a simple random sample of 5050 adult americans and asks them whether or not they support the proposed changes. to say that the distribution of the sample proportion of adults who respond? yes, is approximately? normal, how many more adult americans does the researcher need to sample in the following? cases? ? (a) 10? % of all adult americans support the changes ? (b) 15? % of all adult americans support the changes

The researcher must add at least 7 more adults to the sample to make it a random and simple distribution.

When the condition of all random values having equal probability occurs then the type of distribution is simple distribution.

Given scenarios:

(a )People who supported the change (p1) is 10% or 0.10

(b) People who supported the change is (p2) 15% or 0.15

The sample size or n is 50.

Therefore, the distribution could be made simple and random with the given formula:

Therefore, for case (a) simple and random distribution would be determined with p  0.10.

Now, for case (b) where p is 0.15 for computing simple and random distribution.

Hence, when 7 more samples would be added to the distribution then it would become a simple and random distribution.

explanation:

the arab empire adopted the muslim religion as their main belief. arabs would influence the people from the territories they invaded towards islam (the muslim belief).

nevertheless, throughout the history of the arab empire, rulers brought intellectual individuals from other religions to their centers of learning. these other foreigners included jews, christians, greeks, persians, and indians.   these resulted in the adoption of important knowledge developed by these cultures by the arabic empire. for example, the works of aristotle were translated from greek to arab and indian scientists brought the numerical concept of "zero" to the arabs.

nowadays, 93% of the arab population is muslim, which at the same time is subdivided in sects including the sunni, zaini, alawi, shia. the remaining 7% is composed mainly of christians.
