An electrical firm manufactures light bulbs that have a lifetime that is approximatelynormally distributed with a mean of 850 hours and a standard deviation of 40 hours. Testthe hypothesis that μ = 850 hours against the alternative, μ # 850 hours, if a random sampleof 25 bulbs has an average life of 842 hours.

find p value and its meaning please A survey of 1000 adults from a certain region asked, "If purchasing a used car made certain upgrades or features more affordable, what would be your preferred luxury upgrade?" The results indicated that 58% of the females and 51% of the males answered window tinting. The sample sizes of males and females were not provided. Suppose that of 600 females, 348 reported window tinting as their preferred luxury upgrade of choice, while of 400 males, 204 reported window tinting as their preferred luxury upgrade of choice. Complete parts (a) through (d) below. a. Is there evidence of a difference between males and females in the proportion who said they prefer window tinting as a luxury upgrade at the 0.05 level of significance? State the null and alternative hypotheses, where π1 is the population proportion of females who said they prefer window tinting as a luxury upgrade and π2 is the population proportion of males who said…
