Evaluation using hypothesis Since we have render surface of n=100 which is greater than 30 indeed we select for Z test for testing the hypothesis. p=no. of favorable responses/sample size ^?p=?P(1-P)/n-1 CV=P+Z* ^?p ?=5% Z=1.96 1. H0: less than 70% of customers ar cheerful with the tariff plan. H1: much than 70% of customers argon commodious with the tariff plan. p=78/100=0.78 H0: P<=0.7 H1: P>0.7 ^?p=?P(1-P)/n-1 ^?p=?0.7(1-0.7)/100-1=?0.21/99=0.046 CV=P+Z* ^?p Cv=0.7+1.96(0.046)=0.79 Since p=0.78<CV=0.79 therefrom freeze off H1 and accept H0 Therefore less than 70% argon convenient with the tariff plans of idea telecom. 2.
