The  cost  of  14  models  of  digitals  cameras  at  a  camera specialty  store  during  2014  was  as follows: 340 450 450 280 220 340 290 370 400 310 340 430 270 380 1. Compute mean, median, mode, first and third quartile. 2.  Compute  the  variance,  standard  deviation,  range,  interquartile  range,  coefficient  of variation, standard error of the mean and Z scores. 3. Determine whether or not there are outliers? Explain. 4. Determine whether or not the data are skewed? If so, how? 5.  Based  on  the  previous  results  what  conclusions  can  you  reach  concerning  the  price  of digital cameras at a camera specialty store during 2014. 6. Construct a 90%, 95%, 99% confidence interval for the population mean cost of digitals cameras. 7. Interpret the meaning of each interval. 8.  What assumption  do  you  need  to  make  about  the  population  of  interest  to  construct  the confidence intervals?
