Click here to view the data table of weights. Click here to view the researcher's results. Click here to view a randomization result. Click here to view a bootstrapping result. Use the reported weights as u, and the measured weights as l2. The hypotheses are Ho:Ha = 0 and H, Ha < 0. Listed in the accompanying table are measured and reported weights (Ib) of random female subjects. Use the listed paired sample data, and assume that the samples are simple random samples and that the differences have a distribution that is approximately normal. A researcher used a 0.05 significance level to test the claim that for females, the measured weights tend to be higher than the reported weights. Complete parts (a) and (b) using the accompanying results. a. Use the given randomization result. Compare the results to those obtained using the researcher's P-value. It appears that by chance, it easy to get a difference like the one obtained, because the estimated P-value is than the significance level. Therefore, the null hypothesis rejected, and there sufficient evidence to support the claim that the measured weights tend to be higher than the reported weights. The conclusion from the randomization result is V the conclusion obtained using the researcher's P-value (Round to three decimal places as needed.) b. Use the given bootstrapping result. Compare the results to those obtained using the researcher's confidence interval.
