From the given box and whisker plot, it can be concluded that since all the percentiles for the varsity students are less than the other students, leading to faster reactions, the data suggests that Catherine and Ana's suspicion is correct.
<h3>What does a box-and-whisker plot shows?</h3>
A box and whisker plot shows three things:
- The 25th percentile, which is the median of the bottom 50%.
- The median, which splits the entire data-set into two halfs, the bottom 50% and the upper 50%.
- The 75th percentile, which is the median of the upper 50%.
For the reaction time of other students, we have that:
- The 25th percentile is of approximately 250 ms.
- The median is of approximately 300 ms.
- The 75th percentile is of approximately 325 ms.
For varsity students, we have that:
- The 25th percentile is of approximately 225 ms.
- The median is of approximately 250 ms.
- The 75th percentile is of approximately 300 ms.
Since all the percentiles for the varsity students are less than the other students, leading to faster reactions, the data suggests that Catherine and Ana's suspicion is correct.

Answer:
The test results support the claim
Step-by-step explanation:
The Coca-Cola Company reported that the mean per capita annual sales of its beverages in the United States was 423 eight ounce servings (Coca-Cola Company website, February 3, 2009).
Suppose you are curious whether the consumption of Coca-Cola beverages is higher in Atlanta, Georgia, the location of Coca-Cola’s corporate headquarters.
A sample of 36 individuals from the Atlanta area showed a sample mean annual consumption of 460.4 eight ounce servings with a standard deviation of s = 101.9 ounces. Using α = .05, do the sample results support the conclusion that mean annual consumption of Coca-Cola beverage products is higher in Atlanta?
Hx: u <= 423 oz
Ha: u > 423 oz (claim)
z(460.4) = (460.4-423)/[101.9/sqrt(36)] = 2.2022
p-value = P(z > 2.2022) = 0.0138
Conclusion: Since the p-value is less than 5%
reject Hx at the 5% significance level.
The test results support the claim.
Based on the information given, the probability of getting an odd or even number will be 0.5.
<h3>
How to solve probability.</h3>
From the question given, a die is rolled once, a is the event of rolling an even number and b is the event of rolling an odd number.
A die has 6 numbers. There are 3 odd numbers and 3 even numbers.
Therefore, the probability of getting the odd or even numbers will be:
= 3/6 = 0.5
