A reasarcher is testing a hypothesis of a single mean. the critical Z value for alpha =.05 and a two -tailed test is +1.96 the observed z value from sample data is -2.11 the decision made by the reasarcher based on this information is to the null hypothesis

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

the 3rd on is correct
