Question

Test the hypothesis using the​ P-value approach. Be sure to verify the requirements of the test. Upper H 0 : p equals 0.91 versus Upper H 1 : p not equals 0.91 n equals 500 comma x equals 450 comma alpha equals 0.05 Is np 0 left parenthesis 1 minus p 0 right parenthesis greater than or equals 10​? Select the correct choice below and fill in the answer box to complete your choice. ​(Type an integer or a decimal. Do not​ round.) A. ​Yes, because np 0 left parenthesis 1 minus p 0 right parenthesisequals nothing. B. ​No, because np 0 left parenthesis 1 minus p 0 right parenthesisequals nothing. I need to know how to get the answer to the part on how to get the correct answer for the test statistic please. e

Answer 1

hypothesis:-

given data and some necessary calculations are:-

requirements for the test:-

our decision be:-

​Yes, because

[ we know that for doing 1 proportion z test the necessary assumption is ]

test statistic be:-

p value be:-

[ as this is a two tailed test]

[ from standard normal table]

0.435

decision:-

p value = 0.435 > 0.05 (alpha)

we do not reject the null hypothesis as the p value is greater than .
