suppose h i equals the number of points lindsey scored in the ieth basketball game so far this season, and h1=14, h2=12, h3=18, h4=14, h5=18, h6=19, h8=16
which expression represents the mean number of points scored per game.
a)7
E hi
i=1/7
b)8
E hi
i=1/8
c) 1
E hi
i=8/8
d) 8
E hi2
i=7/8
I don't understand the notation or the E symbol. All they are asking for is the average number of points scored per game. Take the sum of the hi values and divide by 8.
To find the mean number of points scored per game, we need to calculate the average or the sum of all the points scored and divide it by the total number of games played.
The total number of games played can be determined by the given values of h1, h2, h3, h4, h5, h6, and h8. Since h7 is not given, we can assume it as 0 because there is no mention of the points scored in the 7th game in the question.
Therefore, the total number of games played is 8.
To find the sum of all the points scored, we add up the given values of h1, h2, h3, h4, h5, h6, and h8.
Sum of points scored = h1 + h2 + h3 + h4 + h5 + h6 + h8
= 14 + 12 + 18 + 14 + 18 + 19 + 16
= 111
Now, we can calculate the mean number of points scored per game using the formula:
Mean number of points scored per game = Sum of points scored / Total number of games played
= 111 / 8
= 13.875
So, the correct expression that represents the mean number of points scored per game is:
d) 8 * (∑hi^2) / i = 7/8
