Among the participants in group B, the percentage of individuals who had colds that lasted a week or more is 52%, which is the same as the percentage of participants in group A who had colds that lasted a week or more.

Among participants who had colds that lasted a week or more, 100% were in group B. This is because the information provided states that all participants in this category were in group B.

Among all the participants, 14% had a cold that lasted less than a week and were in group A. Therefore, approximately 86% of the participants had a cold that lasted less than a week and were in group B. This corresponds to a total of approximately 37 participants.

To determine the number of participants in group B who had colds that lasted a week or more, we need to complete the table provided with the corresponding percentages. From the information given, we know that 48% of participants in group A had colds that lasted less than a week.

1. Calculate the percentage of participants in group A who had colds that lasted a week or more:

Since the percentage of participants in group A who had colds that lasted less than a week is 48%, the percentage of participants in group A who had colds that lasted a week or more is 100% - 48% = 52%.

2. Calculate the number of participants in group B who had colds that lasted a week or more:

To determine the number of participants in group B who had colds that lasted a week or more, we need to find the equivalent percentage in group B. Since the researchers want to know the percentage among people whose colds lasted less than a week, we need to consider the percentage of participants in group A who had colds that lasted a week or more.

Since the percentage of participants in group B who had colds that lasted a week or more is equivalent to the percentage of participants in group A who had colds that lasted a week or more, we can fill in the corresponding percentage in the table for group B as 52%.

In conclusion, by analyzing the given information and completing the table, we can determine that 52% of participants in group B had colds that lasted a week or more.

To determine the percentage of participants who were in group B and had colds that lasted a week or more, we need to complete the table provided with the corresponding percentages. From the information given, we know that 37% of participants who had colds that lasted less than a week were in group A.

1. Calculate the percentage of participants who had colds that lasted a week or more in group A:

Since the percentage of participants who had colds that lasted less than a week in group A is 37%, the percentage of participants who had colds that lasted a week or more in group A is 100% - 37% = 63%.

2. Calculate the number of participants who had colds that lasted a week or more in group A:

To determine the number of participants who had colds that lasted a week or more in group A, we need to multiply the percentage (63%) by the total number of participants who had colds that lasted less than a week (16+27 = 43).

Number of participants in group A who had colds that lasted a week or more = 63% of 43 = 0.63 * 43 ≈ 27.

3. Calculate the number of participants who were in group B and had colds that lasted a week or more:

Since the total number of participants who had colds that lasted a week or more is given as 27, and we know that all of them were in group B, we can fill in the corresponding box in the table for group B as 27.

In conclusion, by analyzing the given information and completing the table, we can determine that 100% of participants who had colds that lasted a week or more were in group B.

To determine the percentage of participants who had a cold that lasted less than a week and were in group B, we can use the information provided in the table.

1. Calculate the total number of participants who had a cold that lasted less than a week:

To find the total number of participants who had a cold that lasted less than a week, we sum the numbers in the "group A" and "group B" columns for this category: 16 + 27 = 43.

2. Calculate the percentage of participants who had a cold that lasted less than a week and were in group B:

We are given that 14% of all participants had a cold that lasted less than a week and were in group A. To find the percentage of participants who were in group B, we subtract the percentage in group A from 100%: 100% - 14% = 86%.

3. Calculate the number of participants who had a cold that lasted less than a week and were in group B:

To find the number of participants who had a cold that lasted less than a week and were in group B, we multiply the percentage (86%) by the total number of participants who had a cold that lasted less than a week (43).

Number of participants in group B who had a cold that lasted less than a week = 86% of 43 = 0.86 * 43 ≈ 37.
