Question

3.) For this problem you need to generate data so open the probability simulator on the TI calculator and set your seed (Use last 4 digits of your GCID). Select the Roll Dice simulator and set the number of trials to 16, and the number of Sides to 12. Execute Roll and save Data to a list. PROB SIM APP Call the corresponding random variable X. Settings Trial Set: 16 Dice: 1 2 3 Sides: 6 8 10 12 20 Graph: Freg Prob Store Table: No All 50 Clear Table: Yes No Update After: 1 20 50 End SEED NUMBER: 3932 Data: ESC ADVI OK 7 10 7 3 11 11 8 8 2 7 8 2 7 10 6 5 Calculate the following statistics from your data: a.) the sample mean, X = 7 b.) the sample standard deviation, Sy = 4.5460 c.) the median: 7 d.) the Inter Quartile Range, IQR= 5.25 e.) Is the data distribution skewed left? right? or is it symmetric? Answer:

Answer 1

Q3) e) The data is symmetoic, because here g=median - 7 25) form the we have., X_7 and population standard deviation is Oxs 11:13 0.963) 12 Here da l- confidence Level = 1-0.90 = 0 1. i 2c = Coitical value 1.64 $ n = 16 = Number of torials 90% confidence interval for population mean is given by a The t » t Lc * TX un f 1.64 * 111.13/12 V16 3 (7 + 0.3948579) (6.6051421, 7.3948579) CI : (6-6051421,7-3948579 b) 90 The 90% confidence_level mean, we are 90%_confident that our population will lies in interval.
