b) In the table below, 55 students have been placed in four cells according to their lecture's ratings as good performer and poor performers, and success/failure on a consumer intelligence index test item. Lecture's Ratings Good performers Poor performers Total Failure 10 16 26 Test Item Success 15 14 29 Total 25 30 55 Test at 95% confidence Interval whether there is item differences between individuals on the basis of their performance as rated by their teachers. c) Eighteen packets of Dangote Cement had their contents measured for weight. The markings on the packets indicated that the weights were 150 kilograms each. The measured weights are as shown below: 150.2kg 149.5kg 150.0kg 149.5kg 150.2kg 149.5kg 150.0kg 148.8kg i. Calculate and estimate: A. The population mean and, B. The population standard deviation of all the cement of the Dangote brand. ii. Construct a 99% confidence interval of the mean weight of the Dangote cement. Test the hypothesis that the mean weight of a packet of Dangote cement is 150kg at 5% level of significance.
