Caffeine is the world's most widely used stimulant, with approximately 80% consumed in the form of coffee. Participants in a study investigating the relationship between coffee consumption and exercise were asked to report the number of hours they spent per week on moderate (e.g., brisk walking) and vigorous (e.g., strenuous sports and jogging) exercise. Based on these data the researchers estimated the total hours of metabolic equivalent tasks (MET) per week, a value always greater than 0. The table below gives summary statistics of MET for women in this study based on the amount of coffee consumed.

Could you please answer part a and b and then fill in the table. I don't need explanation or work for the table just a and b thank you

Caffeine is the world's most widely used stimulant, with approximately 80% consumed in the form of coffee. Participants in a study investigating the relationship between coffee consumption and exercise were asked to report the number of hours they spent per week on moderate (e.g., brisk walking) and vigorous (e.g., strenuous sports and jogging) exercise. Based on these data the researchers estimated the total hours of metabolic equivalent tasks (MET) per week, a value always greater than 0. The table below gives summary statistics of MET for women in this study based on the amount of coffee consumed. Caffeinated coffee consumption 2-6 cups/week 1 cup/day 2-3 cups/day > 4 cups/day <1 cup/week 18.7 Total Mean 19.6 19.3 18.9 17.5 SD 21.1 25.5 22.5 22.0 22.0 12,215 6,617 17,234 12,290 2,383 50,739 (a) Write the hypotheses for evaluating if the average physical activity level varies among the different levels of coffee consumption.
