The value of the z score is 1.03.
According to the statement
we have given that the value of mean and standard deviation and we have to find the value of the z score.
So, For this purpose we know that the
Z-score indicates how much a given value differs from the standard deviation. The Z-score, or standard score, is the number of standard deviations a given data point lies above or below mean.
And the given values are:
mean value = 69 inches
s.d value = 2.8 inches
And the value of x is 71.9 inches.
So, The Z score is
z = x - mean / standard deviation
substitute the values in it then
z = 71.9 - 69 / 2.8
then
z = 2.9 /2.8
z = 1.03
So, The value of the z score is 1.03.

For this, you just need to add up the team points together. Also remember that the problem says "60 pts or less", not "less than 60 pts". This means teams with 60 pts will count for the question.
Team 1: 
Team 2: 
Team 3: 
Team 4: 
From the math above, we can conclude that 2 teams had won 60 or less.
