| July 29, 2018

Begin by writing an opening paragraph where you summarize the statistical concepts you have learned this week and how you plan to intergrate those concepts into this task.2. Complete the hypothesis test for all adults (men and women) by performing the following steps. Use a level of significance of alpha = 0.05a) Sketch the sampling distribution.b) Determine the critical values and add them to your sketch.c) Determine the rejection regions and shade them in your sketchd) Find the standardized test statistic. Add it to your sketch.e) Make a decision to reject or fall to reject the null hypothesis.f) Interpret the decision in the context of the original claim.3. If you lower the level of significance to alpha = 0.01 does your decision change? Explain your reasoning.4. Test the hypothesis that the mean temperature of men is 98.6o F. What can you conclude at a level of significance of alpha = 0.01.5. Test the hypothesis that the mean temperature of women is 98.6o F. What can you conclude at a level of significance of alpha = 0.01.6. Use the sample of 130 temperatures to form a 99% confidence interval for the mean body temperature of adult humans.7. The conventional “normal” body temperature was established by Carl Wunderlich over 100 year ago. What, in Wunderlich’s sampling procedure, do you think might have led him to an incorrect conclusion?
