Picture1.pngPicture2.pngA. Report the test statistic and p-value and provide their interpretation. Test statistic= [BLANK-1] Test statistic interpretation: the (sample mean/sample proportion) [BLANK-2] is [BLANK-3] standard errors [BLANK-4](above/below) the null hypothesis value of $[BLANK-5]. p-value=[BLANK-6], (do not round, report as you see) p-value interpretation: there is a [BLANK-7]% chance of getting a test statistic of [BLANK-8] (or more extreme) by random chance alone. B. Report the decision and conclusion in context for the test. Decision: Based on a p-value, we [BLANK-9] (Reject / Fail to reject) the null hypothesis since p-value is [BLANK-10] (smaller/greater) than [BLANK-11]%. Conclusion: Therefore, we have [BLANK-12] (evidence/ no evidence) that the parameter is significantly [BLANK-13](lower/higher/different) than [BLANK-14]. C. Is this result trustworthy? [BLANK-15] YES NO (select one) Use words/phrases as presented to answer questions to avoid point deductions Use appropriate symbols to state null and alternative and the signs "=", ">", "
