Question

1. during the first seven days in march 2025, high temperatures were recorded, in degrees fahrenheit, in one particular city. this data is presented in the graph below. based on what is shown in this graph, which one of the following statements is correct? a. the graph proves there is an overall warming effect in this city given that there is generally an increase in temperature across the seven days. b. the recorded high temperature on day 5 is over three times larger than the recorded high temperature on day 1. c. the graph suggests that temperatures change in a consistent way across the seven - day period. d. we should describe this distribution of data as being bimodal since there are many ups and downs being depicted across the seven - day period. e. none of the above statements are correct.

Explanation:

Step1: Analyze option A

The temperature has ups - and - downs over the seven - day period, not a general increase. So option A is incorrect.

Step2: Analyze option B

The temperature on Day 1 is around 42.5°F and on Day 5 is around 60°F. $60\div42.5\approx1.41\lt3$. So option B is incorrect.

Step3: Analyze option C

The temperature has fluctuations (up - and - down changes) and is not changing in a consistent way. So option C is incorrect.

Step4: Analyze option D

A bimodal distribution has two distinct peaks. The graph does not show two distinct peaks for the temperature data over the seven - day period. So option D is incorrect.

Answer:

E. None of the above statements are correct.
