What is normal, when it comes to people's body temperatures? A random sample of 130 human body temperatures had a mean of 98.15º and a standard deviation of 0.72º. Does the data indicate that the average body temperature for healthy humans devia from 98.6°, the usual average temperature cited by physicians and others? (a) Test using the p-value approach with a = 0.05. State the null and alternative hypothesis. O Ho: 98.6 versus H: = 98.6 O Ho: < 98.6 versus H: > 98.6 O Ho: = 98.6 versus H₂: μ = 98.6 ⒸH₂:μ = 98.6 versus H₂: μ> 98.6 Ho: μ = 98.6 versus H₂: μ< 98.6 Find the test statistic and the p-value. (Round your test statistic to two decimal places and your p-value to four decimal places.) p-value= State your conclusion. O The p-value is greater than alpha so Ho is not rejected. There is insufficient evidence to indicate that the average body temperature for healthy humans deviates from 98.6º. O The p-value is less than alpha so Ho is rejected. There sufficient evidence to indicate that the average body temperature for healthy humans deviates from 98.6º. O The p-value is less than alpha so H is rejected. There is insufficient evidence to indicate that the average body temperature for healthy humans deviates from 98.6°. O The p-value is greater than alpha so Ho is not rejected. There is sufficient evidence to indicate that the average body temperature for healthy humans deviates from 98.6º. (b) Test using the critical value approach with a = 0.05. Find the rejection region. (Round your answers to two decimal places. If the test is one-tailed, enter NONE for the unused region.) State your conclusion. O The test statistic does not lie in the rejection region so Ho is not rejected. There is insufficient evidence to indicate that the average body temperature for healthy humans deviates from 98.6°. O The test statistic lies in the rejection region so Ho is rejected. There is sufficient evidence to indicate that the average body temperature for healthy humans deviates from 98.6º. O The test statistic lies in the rejection region so Ho is rejected. There is insufficient evidence to indicate that the average body temperature for healthy humans deviates from 98.6º. O The test statistic does not lie in the rejection region so H is not rejected. There is sufficient evidence to indicate that the average body temperature for healthy humans deviates from 98.6°.
