Question
1) Perform the hypothesis test to test the claim that u 98.6 (this is what is believed to be normal body temperature). Include the following to support your results: The critical value(s) used for this hypothesis test, assuming a -0.05. 1.960, 1.960 The value of your test statistic, rounded to three decimal places. -5.467 A statement about whether or not your test statistic falls into the critical region. The test statistic does fall within the critical region Your decision to reject or not reject the null hypothesis l would reject this as it does fall in the rejection region. Your conclusion, in your own words. Keep in mind what the claim is when you word your conclusion 2) Assuming the same claim and data as in #1, change the level of significance to a -0.01. What are the new critical values? -2.576, 2.576 Do your decision and conclusion from #1 change? No After examining the data, one may think that the men and women's samples have much different means. This next part will address this by doing a 2-sample hypothesis test, much like you did in chapter 8. 3) Taking the men's and women's data separately, find the mean and standard deviation of each sample. Round your final answers to the nearest hundredth Men: Mean 98.11 Standard deviation: 0.69 Women: 98.39 Standard deviation of sample is 0.74 4) Test the claim that the two groups have equal respective population means (Au us). Provide the following to support your claim. The critical value(s) used for this hypothesis test, assuming a 0.05 1.960, 1.960 decimal places. The value of your test statistic, rounded to three A statement about whether or not your test statistic falls into the critical region. Your decision to reject or not reject the null hypothesis. Your conclusion, in your own words. Keep in mind what the claim is when you word your conclusion.Explanation / Answer
1.) The critical value of z at 0.05 level of significance is 1.96 or -1.96
If the z score is less than or equal to the critical value , we reject the null hypothesis .
2.)z score at level of significance 0.01 is 2.33 , if the value of z score lies between -2.33&2.33 we reject the null hypothesis.
