Question

question 4 (1 point)(05.02 lc)two groups of students were asked how far they lived from their school. the table shows the distances in miles:group a (distance in miles) 1 1.5 3.03 3.2 2.8 1.5 1.8 2.5 2.2group b (distance in miles) 2 2.5 3.23 1.3 1.8 2.43 1.5 1.8which statement best compares the mean distances for the two groups?a it is equal for group a and group b.b it is greater for group b than group a.c its value for group a is double the value for group b.d its value for group b is double the value for group a.

Explanation:

Step1: Calculate sum of Group A

$1 + 1.5 + 3.03 + 3.2 + 2.8 + 1.5 + 1.8 + 2.5 + 2.2 = 19.53$

Step2: Find mean of Group A

Mean = $\frac{\text{Sum}}{\text{Number of data points}} = \frac{19.53}{9} = 2.17$

Step3: Calculate sum of Group B

$2 + 2.5 + 3.23 + 1.3 + 1.8 + 2.4 + 3 + 1.5 + 1.8 = 19.53$

Step4: Find mean of Group B

Mean = $\frac{19.53}{9} = 2.17$

Step5: Compare the two means

The means of Group A and Group B are equal.

Answer:

a. It is equal for Group A and Group B.
