# Data Analysis : Null Hypotheses and Normal Distribution

A random sample of 8 petrol stations in each of three European countries A, B and C was taken. The price per litre at each station was recorded in Euros. The prices are given below.

A 7.80 8.00 7.98 8.20 8.00 7.99 8.10 7.90

B 8.01 7.75 8.00 7.77 8.01 8.01 8.12 8.20

C 8.10 7.92 8.01 7.88 8.30 8.22 8.56 8.10

Discuss ways of analysing this data from the point of view of having a standard price for petrol in the EU.
