The following are the data of weights (in kg) of a random sample of 7 women swimmers. 73 76 67 60 56 63 74
[h] Consider the weight data in part {a} that were taken from women swimmers in NEW, Australia. i. Test at the 10% level of signicance, to see if the data supports the claim that the average weight of women swimmers in NSW is less than 1'1 kg.
