Explanation:

Step1: Calculate total number of meals

$160 + 120+120=400$

Step2: Calculate relative frequency of breakfast

$\frac{160}{400}\times100\% = 40\%$

Step3: Calculate relative frequency of lunch

$\frac{120}{400}\times100\%=30\%$

Step4: Calculate relative frequency of dinner

$\frac{120}{400}\times100\% = 30\%$

Step5: Draw bar - graph

On the x - axis, label "Meal" with categories "Breakfast", "Lunch", "Dinner". On the y - axis, label "Relative Frequency (%)" with values from 0 to 50. Draw a bar for breakfast reaching up to 40%, a bar for lunch reaching up to 30%, and a bar for dinner reaching up to 30%.

Answer:

Relative frequencies: Breakfast is 40%, Lunch is 30%, Dinner is 30%. Bar - graph with x - axis labeled "Meal" (Breakfast, Lunch, Dinner) and y - axis labeled "Relative Frequency (%)" having bars at 40%, 30%, 30% respectively.
