According to historical data, it is believed that 12% of american adults work more than one job. to investigate if this claim is still accurate today, a random sample of 100 american adults is selected. it is discovered that 18 of them work more than one job. a researcher would like to know if the data provide convincing evidence that the true proportion of american adults who work more than one job differs from 12%. the standardized test statistic is z = 1. 85 and the p-value is 0. 0644. what decision should the researcher make using the α = 0. 05 significance level? reject h0 because the p-value is greater than α = 0. 05. reject ha because the p-value is greater than α= 0. 05. fail to reject h0 because the p-value is greater than α = 0. 05. fail to reject ha because the p-value is greater than α = 0. 05.
a) Reject H0 because the p-value is greater than α = 0. 05.
b) Reject Ha because the p-value is greater than α = 0. 05.
c) Fail to reject H0 because the p-value is greater than α = 0. 05.
d) Fail to reject Ha because the p-value is greater than α = 0. 05.
