Pls do fast and i will like for sure Try to give solution in typed form.. Given is the mean and Average deviation. There is no standard deviation given, How are you able to get percent relative standard deviation with out it?

An ore sample was analyzed for its Fe content. Student A analyzed the sample a total of six times and her results had a standard deviation of 1.33. The same sample was analyzed five times by Student B and his results had a standard deviation of 3.42. To determine if their standard deviations are similar, they perform an F test. The calculated F value is and the table value of Fis 3 in your book for critical values of F. O 6.61; 7.39 O 6.61; 9.36 O 0.151; 9.36 O 2.57; 7.39 O 6.61; 6.98 Refer to Table 4-

9. The following are three sets of data for the atomic mass on antimony (Sb) from the work of Willard and McAlpine. Set 1 Set 2 Set 3 121.771 121.784 121.752 121.787 121.758 121.784 121.803 121.765 121.765 121.781 121.794 a) Determine the mean and standard deviation of each data set. b) Determine the 95% confidence intervals for each data set. c) Determine whether the 121.803 value in Set 1 is an outlier for that set. d) Pool the data and determine the overall mean and the pooled standard deviation. e) Compare the overall mean of the 11 data points with the currently accepted value. Report the absolute error and the percent relative error, assuming the currently accepted value is the true value.

Can you please fill the rest of tghe data based on the on inforamtion you have and  answer  Average concentratuon of NaOH  Standard deviation of concentration
