Question

Rasmussen College - STA3215 - Module 3 Homework

1. A formal hypothesis test is to be conducted using the claim that the mean body temperature is equal to 98.6 degrees Fahrenheit.

a. Identify the symbolic form of the null hypothesis.

b. Identify the symbolic form of the null hypothesis.

c. Is the test two-tailed, left-tailed or right-tailed? Explain.

d. What possible conclusions can be made about the null hypothesis?

e. After performing the hypothesis test, the p-value is found to be 0.034. Using a significance level of 0.05, should you reject or fail to reject the null hypothesis? Explain.

f. If the decision was to reject the null hypothesis, how would you state the final conclusion that addresses the original claim?

Answer 1

1.)

a.) Null Hypothesis, H₀ : μ=98.6 degrees Fahrenheit

b.) Alternative Hypothesis, H_a : μ  ≠ 98.6 degrees Fahrenheit

c.)It is two tailed Test, As Alternative Alternative Hypothesis, H_a : μ  ≠ 98.6, it means mean body temperature can be either<98.6 or >98.6

d.)Before performing the Hypothesis test the mean body temperature is 98.6 degree Fahrenheit

e.)p-value<Significance (0.05), reject the null hypothesis,because rejection region p-value<0.05

f.)There is sufficient evidence to support the claim that the mean body temperature is not equal to 98.6 degrees Fahrenheit.
