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]
