Question

as part of a statistics lesson, miss hamilton asked her students how many jackets they own.
jackets
(plot with xs for number of jackets: 0 has 8 xs, 1 has 1 x, 2 has 5 xs, 3 has 9 xs, 4 has 4 xs, 5 has 0 xs, 6 has 7 xs)
number of jackets
how many students own at least 5 jackets?

Explanation:

Step1: Identify relevant columns

We need to look at the number of jackets equal to 5 and 6 (since "at least 5" means 5 or more). From the dot plot, the column for 5 has 0 X's (no students) and the column for 6 has 7 X's (let's count: looking at the plot, for 6 jackets, the number of X's is 7? Wait, wait, let's re - examine. Wait, the x - axis is 0,1,2,3,4,5,6. For 5 jackets: how many X's? Looking at the plot, the column for 5 has 0 (since there are no X's there). For 6 jackets: let's count the X's. The column for 6 has 7? Wait, no, let's look again. Wait, the plot:

  • 0 jackets: 8 X's (let's count: the first column, 0, has 8 X's? Wait, no, let's count each column:

0: X X X X X X X X (8)

1: X (1)

2: X X X X X (5)

3: X X X X X X X X X (9? Wait, no, the original plot: let's see, the user's plot:

"Jackets" dot plot:

0: 8 X's (let's count the vertical X's: first column, 0, has 8? Wait, no, maybe I misread. Wait, the problem is "at least 5", so 5 and 6.

Looking at the plot:

  • 5 jackets: how many X's? The column for 5 (the fifth column after 0,1,2,3,4) has 0 (no X's).
  • 6 jackets: the column for 6 has 7 X's? Wait, no, let's count the X's for 6. Let's see the X's in the 6 column: looking at the plot, the 6 column has 7 X's? Wait, maybe I made a mistake. Wait, the correct way: "at least 5" means number of jackets ≥5, so we consider the number of students with 5 jackets and 6 jackets.

From the dot plot:

  • Number of students with 5 jackets: 0 (since there are no X's above 5 on the x - axis).
  • Number of students with 6 jackets: let's count the X's in the 6 column. Looking at the plot, the 6 column has 7 X's? Wait, no, let's look again. Wait, the user's plot:

For 6 jackets, the X's are: let's count the vertical X's. Let's see, the 6 column has 7 X's? Wait, maybe I miscounted. Wait, the correct count:

Looking at the plot:

  • 0: 8
  • 1: 1
  • 2: 5
  • 3: 9
  • 4: 4
  • 5: 0
  • 6: 7

Wait, no, maybe the 5 column has 0 and 6 column has 7. So total students with at least 5 jackets is 0 + 7=7? Wait, no, maybe I made a mistake. Wait, the key is "at least 5", so 5 or more. So we sum the number of X's for 5 and 6.

Looking at the plot:

  • 5 jackets: 0 (no X's)
  • 6 jackets: 7 (let's count the X's in the 6 column: the vertical X's, there are 7). So 0 + 7 = 7? Wait, no, maybe the 5 column has 0 and 6 has 7. So the total is 7.

Wait, maybe I misread the 5 column. Let's check again. The x - axis is 0,1,2,3,4,5,6. So 5 is the sixth category (0 is first, 1 second, 2 third, 3 fourth, 4 fifth, 5 sixth, 6 seventh). The 5th column (after 0 - 4) is 5, and it has 0 X's. The 6th column (6) has 7 X's. So 0+7 = 7.

Step2: Sum the counts

Number of students with 5 jackets: 0

Number of students with 6 jackets: 7

Total = 0 + 7=7

Answer:

7
