The indoor air temperature (C) measured in two shops (Tas1 and Tas2) are recorded and shown in table

(i) Please estimate the measures of central tendency of the two variables (Tas1 and Tas2). Then, please estimate the measures of spread of the variables of the two variables (Tas1 and Tas2).

(ii) Would an additional observation of 16C be identified as an outlier for shop 1? Would an additional observation of 16C be identified as an outlier for shop 2? Briefly describe your results.

(iii) Is indoor air temperature significantly different between the two shops? Please apply the appropriate inferential test and briefly describe your results.
