Answer the following multiple choice questions:

Suppose that you wish to model the lifetime of a certain type of LED light bulb. Let Y represent the lifetime of a randomly selected bulb (in hours). An Exponential model with mean 9 has been proposed. Suppose that a random sample of sixty of these LED light bulbs yielded an average lifetime of 8,624.75 hours. Assume that the lifetime of each bulb is independent of all other lifetimes. M In order to test Ho: 0 = 10,000 (versus the two-sided alternative), a likelihood ratio test is to be conducted. Which of the following statements would be used in R to produce the approximate p-value, based on the observed data? A) 1 - pchisq(1.2509, 1) B) 2*pnorm(1.2509) - 1 C) 2*(1-pnorm(1.1184)) D) 2*(1-pnorm[1.2509) 1) E) 2*pchisq(1.2509,1) - 1 F) More than one of these statements could be used to produce the approximate p-value b) Using an approximate Normal test statistic, calculate the approximate p-Value in order to test Ho (versus the two-sided alternative). You can assume that the Central Limit Theorem holds. A) 0.217 B) 1.235 C) 1.065 D) 0.287 E) 0.143
