Question 19 of 25 • Probability and Statistics with Applications Honors Sem-2-FL-1210300 (2024-2025)
On average, a person’s body temperature should be approximately 98.6°F. A doctor would like to test the hypotheses = 98.6 versus 98.6 where μ = the true mean body temperature of all adults. Before conducting the test, the doctor determines that the power of the test to reject the null hypothesis when μ = 98 using α = 0.01 and n = 10 is 0.2474. What combination of sample size and significance level would increase the power of this test the most?
Answer
A
use n = 5, alpha = 0.05
B
use n = 5, alpha = 0.10
C
use n = 20, alpha = 0.05
D
use n = 20, alpha = 0.10
