Question

Test the hypothesis using the​ P-value approach.
Upper H 0 : p equals 0.50 versus Upper H 1 : p less than 0.50
n equals 150 comma x equals 66 comma alpha equals 0.10
Perform the test using the​ P-value approach.
​P-valueequals
nothing ​(Round to four decimal places as​ needed.)

Answer 1

Null hypothesis  

               
                  
Alternative hypothesis          

       
                  
We have for given example,                  
Population proportion value is =0.5              
x=66              
                  
n=150              
Level of significance =   0.1              
Estimate for sample proportion =0.44              
                  
Z test statistic formula for proportion                  


=-1.47  

P value = 0.0708..................by using Z table or Excel =NORMSDIST(-1.47)

P value < 0.10

Therefore, we reject H0 at
