Incorrect
Step-by-step explanation:
This interpretation is incorrect because it states that 98% of the data is with in the confidence interval.

<u>Explanation</u></h3>
The structure or equation is similar to a quadratic function.
The value of a determines the slope of graph.
Tthe value of h determines the horizontal shift of graph.
The value of k determines the vertical shift of the graph.
From the given equation,
We can say that the graph shifts to the right 2 units and shifts down 7 units. Hence the vertex would be at x = 2 and y = -7. It can be written in coordinate form as (2,-7).

Answer:
75%
Step-by-step explanation:
If Mitchell took a math exam and got 63 out of 84 questions correct, that would turn into the fraction: 63/84
In order to convert this to a decimal, you divide 84 by 63 (since every fraction is a division problem), and get 0.75.
When you change decimals into percents, you move the decimal point two times to the right. So, that would be 75.
Then you add the percent symbol and you're done!
I hope that helped :)
