7. A Random Variable X has an unknown distribution, a known mean of 10 and an unknown variance, o. To test a claim that the distribution is no longer 10, a random sample of 100 of X was collected which gave a sample mean, x of 9.8 and a sample variance, s? = 16. Which of these is the appropriate Null and Alternative hypothesis? A. Η: μ= 10 ; Η: μ# 10. B. Η μ- 10 ; H: μ< 10. C. Η: μ- 10; Η: μ> 10. D. x= 10 ; H1: x± 10. 2
