Aresearcher evaluates a treatment effect using a two-tailed hypothesis test with a = .05, and the decision is to reject the null hypothesis. if the researcher used the same sample and switched to a one-tailed test that is consistent with the direction found in initial two-tailed hypothesis test, what decision would be made?

if the researcher switches to a one tailed test, the decision will be to definitely reject a= 0.05 and maybe reject a=0.01

Explanation:

in data analysis, the 0.05 means a 95% confidence level and 0.01 means a 1% confidence level. since the decision is to reject the null hypothesis at 95% confidence level and a one-tailed test has the entire 5% on one side, anything  equal to 0.05 and above, the null hypothesis should be totally rejected.

on the other hand, in a two tailed the 5% is split on both sides of the tail.

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.
