A study published in 2008 reported that the mean weight of men aged 40-59 was 89.3 kg. Another study, published in 2016, reported that a sample of 192 men aged 40-59 had an average weight of 88.2 kg. Assume the population standard deviation is o= 14.3 kg. Can you conclude that the mean weight of men aged 40-59 is different in 2016 than in 2008? Use the a=0.10 level of significance
