A randongation dstrbution for this test shows SE = 0.013 lgew Research Certer,'Internet Gains Television as peles Man News Sorr. )anuary 4, 2011. State the null and aternative hypotheses P2 Click here to start 0.65 Ho:Explanation / Answer
H0: P = 0.65
H1: P > 0.65
Z = (p - P)/SE
= (0.66 - 0.65)/0.013
= 0.77
P-value = P(Z > 0.77)
= 1 - P(Z < 0.77)
= 1 - 0.7794
= 0.221
As the p-value 0.221 is greater than the alpha value 0.05, so the null hypothesis is not rejected.
Don't reject H0.
No, we don't find the evidence that more than 65% of all adults use television as one of their main sources of news.
