Question:
The scatter plot shows the maximum noise level when different numbers of people are in a stadium. The linear model is given by the equation y=1.5x + 22.7 where y represents maximum noise level and x represents the number of people, in thousands, in the stadium.
A sports announcer states that there are 65,000 fans in the stadium. Estimate the maximum noise level. Is this estimate reasonable? Explain your reasoning.
Answer:

Step-by-step explanation:
Given


Required
Find y
Substitute 65000 for x in the given equation



<em>It is reasonable because as the population increases, the noise level also increases</em>
Step-by-step explanation:
z = (x − μ) / σ
z = (65 − 69) / 3.5
z = -1.14
