Rpub a company that manufactures light bulbs has advertised that its 75- watt bulbs burn an average of 800 hours before failing. in reaction to the company’s advertising campaign, several dissatisfied customers have complained to a consumer watchdog organization that they believe the company’s claim to be exaggerated. the consumer organization must decide whether or not to allocate some of its financial resources to countering the company’s advertising campaign. so that it can make an informed decision, it begins by purchasing and testing 100 of the disputed light bulbs. in this experiment, the 100 light bulbs burned an average of .x = 745.1 hours before failing, with a sample standard deviation of s = 238.0 hours. formulate null and alternative hypotheses that are appropriate for this situation. calculate a significance probability. do these results warrant rejecting the null hypothesis at a significance level of α = 0.05?
