Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 132 to 191 cm and weights of 41 to 150 kg. let the predictor variable x be the first variable given. the 100 paired measurements yield x hat= 167.82 cm, y hat= 81.39 kg, r = 0.101, p-value = 0.317, and y = - 106 + 1.01x. find the best predicted value of y (weight) given an adult male who is 189 cm tall. use a 0.05 significance level. find the best predicted value of y hat for an adult male who is 189 tall in .

Since the students are to be selected at random, the concept used is Combination. The combination is 20C7 which means that "combination of 20 taken 7". The numerical value of the combination is 77520. Thus, there are 77520 ways of choosing the members of the student council.
