According to Statistics Canada the mean birth weight of newborn babies in Canada is 3.372 kg for both sexes. However, a pediatrician in Alberta believes that mean birth of newborn babies for both sexes in Alberta is much higher than the national average. In this case, the alternative hypothesis is Ha: >3.372 The null hypothesis is Ho: 3.372 If you fail to reject the null hypothesis, then you can conclude that mean birth weight of newborn babies in the province of Alberta is not higher than 3.372 kg. In other words, it is same as the national average.
