4. In the past, the mean running time for a certain type of cell phone battery has been19.2 hours. The manufacturer has introduced a change in the production method andwants to perform a hypothesis test to determine whether the mean running time hasincreased as a result. The hypotheses are:Họ: u=19.2 hoursH1: µ>19.2 hoursExplain the meaning of a Type I error.A) Concluding that u> 19.2 hours when in fact u = 19.2 hoursB) Concluding that u < 19.2 hours when in fact u> 19.2 hoursC) Concluding that u =D) Concluding that u> 19.2 hours when in fact u> 19.2 hours19.2 hours when in fact u > 19.2 hours

Here use definition of type 1 error

Activity 3: Solve Me! Directions: Solve the following problem. Write all your necessary solutions. Survey tests on leadership skills and on self-concept were administered to student-leaders. Both tests use a 10-point Likert scale with 10 indicating the highest score for each test. Scores for the student-leader on the tests follow: E F G 1 J Student Code Self-concept A B C D 9.5 9.3 6.3 4.2 5.3 Leadership skill 9.2 8.9 7.2 8.1 7.7 6.8 5.5 7.1 3.3 6.1 7.8 8.6 7.0 6.5 8.2 1.

22 of 47 > Five strains of the Staphylococcus aureus bacteria were grown for 24 hours either at 35 degrees Celsius or at 43 degrees Celsius. The table gives the resulting bacterial counts for each condition: 24 hours at 35 degrees Celsius 24 hours at 43 degrees Celsius 66 98 71 67 93 42 102 31 62 77 Suppose we had plotted bacterial count at 35 degrees Celsius on the y axis instead of the x axis. How would this change affect the value of the correlation coefficient? The correlation would be the inverse of, or I over, the original value. The correlation coefficient would have the opposite sign. The correlation coefficient would be exactly the same. The correlation coefficient would have an entirely different magnitude.
