Answer:
(5953.52,6046.49)
Step-by-step explanation:
We are given the following in the question:
Mean,
= 6,000 pounds
Sample size, n = 40
Alpha, α = 0.05
Standard deviation, σ = 150 pounds
95% Confidence interval:
Putting the values, we get,
are the limits within which 95% of the sample means occur.
Answer: There is one outlier that indicates an unusually large number of players on that team.
In the data set given, most of the values are around 8 to 12 players on the team. However, one team has 21. That is an outlier. It is an unusually large number of players.
A direct variation suggest that the value of x in the equation would greatly affect the value of y such that when x is increasing, y also increases and the other way around. The equation for a direct variation is that,
y = kx
Substituting the given values in the ordered pair,
5 = k(4) ; k = 5/4
