Answer 1

null Hypothesis alternate Hypothesis: Ho: 0.015 0.015 Ha: for 0.05 level with right tailed test, critical value of z- Decision rule 1.645 reject Ho if test statisticz > 1.645 sample success sample size 800.0 std error -Se (p*(1-p)/n) = 0.0043 sample proportion p 0.0275 test stat = z (p-p)/Se= 2.91 p value 0.002

from above:

Ho: p=0.015

Ha: p>0.015

p value =0.002

option b is correct
