Please no written by hand solution and no img . Pairs of hypotheses about a claim (a statistic of the population, like its mean, μ) include the following: (A) H0: μ ³ k and Ha: μ < k, where k is some value (B) H0: μ = k and Ha: μ ≠ k, where k is some value (C) H0: μ > k and Ha: μ £ k, where k is some value (D) H0: μ £ k and Ha: μ > k, where k is some value (E) H0: μ < k and Ha: μ ³ k, where k is some value
State the conclusion based on the results of the test. The mean of the pressure required to open a certain valve is known to be u = 6.7 psi. Due to changes in the manufacturing process, the quality-control manager feels that the average pressure has changed. The null hypothesis was rejected. Choose the correct answer below. O A. The mean of the pressure has not changed. O B. There is not sufficient evidence that the mean of the pressure required to open a certain valve has changed. O C. There is not sufficient evidence that the mean of the pressure required to open a certain valve has not changed. O D. The mean of the pressure has changed. O E. There is sufficient evidence that the mean of the pressure required to open a certain valve has changed. O F. There is sufficient evidence that the mean of the pressure required to open a certain valve has not changed.
Stoaches are fictional creatures, sometimes mistaken for mome raths. Suppose a two-tailed ? t -test is conducted to test for a difference between the population means of adult female stoach weights and adult male stoach weights. The female sample has 6 weights, and the male sample has 12 weights. The ? t -statistic for the test is -2.69933. What is the ? p -value? (Give your answer to 4 decimal places.)
