Question 10 of 15 < > View Policies Current Attempt in Progress In the same study as was mentioned in the previous two exercises, data were also collected on 65 healthy female volunteers aged 18 to 40 that were participating in the vaccine trials. The data set Female Temps consisting of body temperatures from the 65 females is available from the textbook website. You will use the data to investigate whether the average body temperature of healthy adult females is different from 98.6°F. (a) What are the appropriate null and alternative hypotheses for this study? O Ho: O Ho: O Ho: 98.6°F, H.: 98.6°F 98.6°F, H₂> 98.6°F 98.6°F, H,:<98.6°F -/1 eTextbook and Media
(b) The dotplot below shows the 65 body temperatures. Based on this dotplot, does it appear the average body temperature is different than 98.6°F? Choose the best among the following statements. 96 and the l 98 Body temperatures e Textbook and Media 99 100 101 O Yes, because not all the points are equal to 98.6°F. O No, because the average of the maximum temperature and the minimum temperature is close to 98.6°F O It is hard to tell, because there is a lot of variability in the data.
(c) The sample mean body temperature for the 65 females in our sample is 98.39°F and the standard deviation is 0.743°F. Use the Theory-Based Inference applet to find and report a standardized statistic (t-statistic) and a p-value for the test. Report answers as provided in the applet (no rounding). t-statistic = i and p-value = i eTextbook and Media (d) Choose the best conclusion based on the p-value. O Since the p-value is less than 0.05 we have strong evidence that the average body temperature for females is equal to 98.6 degrees. O Since the p-value is less than 0.05 we have strong evidence that the average body temperature for females is less than 98.6 degrees. O Since the p-value is less than 0.05 we have strong evidence that the average body temperature for females is greater than 98.6 degrees. O Since the p-value is less than 0.05 we have strong evidence that the average body temperature for females is different than 98.6 degrees.
