Question

a company that makes and sells dog food is considering changing its customer rewards program and wants to determine how many customers own multiple dogs. each member of the sales team randomly surveys 10 customers about how many dogs they own here are the data from one salespersons sample, with the number indicating how many dogs a customer owns: 1 1 2 1 1 4 3 2 1 1 what percentage of the customers in this salespersons sample own 2 or more dogs? %

Explanation:

Step1: Count total customers

There are 10 customers surveyed, so total = 10.

Step2: Count customers with ≥2 dogs

Data: 1,1,2,1,1,4,3,2,1,1.
Customers with 2 or more: 2,4,3,2 → that's 4 customers? Wait, no: 2 (1st 2), 4, 3, 2 (second 2) → wait, let's list all:
Numbers: 1 (1), 1 (2), 2 (3), 1 (4), 1 (5), 4 (6), 3 (7), 2 (8), 1 (9), 1 (10).
So positions 3 (2), 6 (4), 7 (3), 8 (2) → 4 customers? Wait no, 2,4,3,2: that's 4? Wait 2 is two dogs, 4 is four, 3 is three, 2 is two. So 4 customers? Wait no, wait the data is 10 numbers: let's count how many are ≥2.
1: no, 1: no, 2: yes, 1: no, 1: no, 4: yes, 3: yes, 2: yes, 1: no, 1: no. So that's 2,4,3,2 → four customers? Wait 2 (third), 4 (sixth), 3 (seventh), 2 (eighth) → four. Wait 4 customers? Wait 10 total. Wait no, wait 2,4,3,2: that's four? Wait 2 is one, 4 is two, 3 is three, 2 is four? Wait no, the count of numbers ≥2: 2 (1), 4 (2), 3 (3), 2 (4). So four customers. Wait but 2,4,3,2: that's four. Wait 10 total. So percentage is (4/10)100 = 40%? Wait wait, no: wait 2,4,3,2: that's four? Wait 2 is two dogs, 4 is four, 3 is three, 2 is two. So four customers. So 4 out of 10. So (4/10)100 = 40%? Wait wait, no, wait let's recheck the data:
Data points: 1,1,2,1,1,4,3,2,1,1. Let's count each:
1: 1 dog (no)
1: 1 dog (no)
2: 2 dogs (yes)
1: 1 dog (no)
1: 1 dog (no)
4: 4 dogs (yes)
3: 3 dogs (yes)
2: 2 dogs (yes)
1: 1 dog (no)
1: 1 dog (no)
So yes: 2,4,3,2 → four customers. So 4/10 = 0.4 → 40%. Wait but wait, is that correct? Wait 2,4,3,2: that's four. So 4/10 = 40%. Wait but maybe I made a mistake. Wait 2 (third), 4 (sixth), 3 (seventh), 2 (eighth) → four. So 4 out of 10. So 40%.

Wait wait, no, wait 2 is two dogs, 4 is four, 3 is three, 2 is two. So four customers. So 4/10 = 0.4 → 40%. So the percentage is 40%.

Answer:

40%
