Using STATCRUNCH please find the pvalue Im not sure how to g
Using STATCRUNCH please find the p-value. I\'m not sure how to get the answer using statcrunch so please include instructions with pictures if possible. Thank you
Solution
Formulating the null and alternatuve hypotheses,          
           
 Ho:   p   =   0.37
 Ha:   p   =/=   0.37
This is a two tailed test.
As we see, the hypothesized po = 0.37
Getting the point estimate of p, p^,          
           
 p^ = x / n =    0.47      
           
 Getting the standard error of p^, sp,          
           
 sp = sqrt[po (1 - po)/n] =    0.03413942      
           
 Getting the z statistic,          
           
 z = (p^ - po)/sp =    2.929165168      
           
 As this is a    2   tailed test, then, getting the p value,  
           
 p =    0.003398738   [ANSWER]
