A recent survey of frozen convenience meals found a correlation of r=0.768 between calories and fat content in the sampled meals. Which of the following is the most appropriate conclusion from this survey about the relationship between calories and fat content?

a. Higher fat content in the sampled meals resulted in a higher total number of calories in the majority of cases in the sample

b. There is not enough evidence of a correlation between the calories and the fat content of the sampled meals to draw a conclusion

c. This survey substantiates the findings of previous research that "higher fat meals tend to produce a larger number of calories."

d. There is a strong correlation between the calorie count and fat content of the sampled meals
