Homework: Section 7.2 Demonstrate (a) Identify the null hypothesis and alternative hypothesis. O A. Ho: μ#766(claim) H₂: μ = 766 A light bulb manufacturer guarantees that the mean life of a certain type of light bulb is at least 766 hours. A random sample of 26 light bulbs has a mean life of 741 hours. Assume the population is normally distributed and the population standard deviation is 60 hours. At α = 0.08, do you have enough evidence to reject the manufacturer's claim? Complete parts (a) through (e). O D. Ho: μ = 741 Ha: μ#741 (claim) Statcrunch
Question 10, 7.2.40-T Part 1 of 5 O B. Ho: <741 (claim) Ha: μ ≥741 O E. Ho: μ≤741 Ha: >741 (claim) HW Score: 8.33%, 1 of 12 points O Points: 0 of 1 C O C. Ho: μ> 766 Ha: H≤ 766 (claim) O F. Ho: μ ≥ 766 (claim) Ha: H <766 Save Clear all Check answer
