Extracted text: W Math 2250 Unit 4 Post Test Re X b Statistics Question | bartleby X + webassign.net/web/Student/Assignment-Responses/last?dep=24515412 A set of solar batteries is used in a research satellite. The satellite can run on only one battery, but it runs best if more than one battery is used. The variance o of lifetimes of these batteries affects the useful lifetime of the satellite before it goes dead. If the variance is too small, all the batteries will tend to die at once. Why? If the variance is too large, the batteries are simply not dependable. Why? Engineers have determined that a variance of o² = 23 months (squared) is most desirable for these batteries. A random sample of 22 batteries gave a sample variance of 15.2 months (squared). Using a 0.05 level of significance, test the claim that o? = 23 against the claim that oʻ is different from 23. (a) What is the level of significance? State the null and alternate hypotheses. of = 23; H,: o² < 23="" h:="" o2="23;" h="" o2="" +="" 23="" h,:="" o2="23;" h,:=""> 23 H,: o² > 23; H7 o2 = 23 (b) Find the value of the chi-square statistic for the sample. (Round your answer to two decimal places.) What are the degrees of freedom? What assumptions are you making about the original distribution? O We assume a binomial population distribution. We assume a normal population distribution. We assume a exponential population distribution. We assume a uniform population distribution.
