The number of people visiting a park over 1 week was recorded. Determine the interval of the group by dividing the data into 5 groups and calculate the mean of the grouped frequency for the data set: (29, 35, 17, 21, 27, 39, 41}.
Interval of the group:
Mean of the grouped frequency to the nearest whole number:

nterval = Upper-Class limit – Lower class limit.

Step-by-step explanation:

nterval = Upper-Class limit – Lower class limit.

Osvoldo did not meet his goal

Step-by-step explanation:

To know the percentage of carbohydrates that Osvoldo ate from grains with respect to the total, we simply have to divide the amount of carbohydrates he got with the grains by the total

55 / 220 = 0.25

then to express it as a percentage this number has to be multiplied by 100

0.25 * 100 = 25%

Osvoldo wanted to reach 30% and only got 25%

25% < 30%
