Statistics problems with solutions
Ha: The actual college majors of graduating females do not fit the distribution of their expected majors. df = 10. chi-square distribution with df = 10. test statistic = 11.48. p-value = 0.3211. Check student’s solution. α = 0.05. Decision: Do not reject null when a = 0.05 and a = 0.01. Reason for decision: p-value > α.The relevant test statistic and p-value can be read off in the R output as 32.7 and 0.000063. So the answer is: Yes, as the relevant test statistic and p-value are resp. 32.7 and 0.00006 < 0.05 = a. b)Give the 95% confidence interval …Problems & Solutions in Mathematicsal Statistics Paperback – 1 January 2019 by Translator) Gupta Vikas Gupta S.C., Gupta Sanjeev Kumar (Author (Author) 4.2 4.2 out …
