The mean weekly allowance is 3.5 dollars
Step-by-step explanation:
Given: Number of students receive no amount =7
Number of students receive $3=5
Then, total amount 5 students receive =![5\times3=\$15](/tpl/images/0490/7369/34733.png)
Number of students receive $5=7
Then, total amount 7 students receive =![5\times7=\$35](/tpl/images/0490/7369/3860a.png)
Number of students receive $6=3
Then, total amount 3 students receive =![6\times3=\$18](/tpl/images/0490/7369/312b2.png)
Number of students receive $8=2
Then, total amount 2 students receive =![2\times8=\$16](/tpl/images/0490/7369/38496.png)
Now, the total amount all students receive=![15+35+18+16=84](/tpl/images/0490/7369/3ab15.png)
The total students =![7+5+7+3+2=24](/tpl/images/0490/7369/3c48b.png)
Now, Mean=![\frac{\text{Total amount}}{\text{Total students}}=\frac{84}{24}=\$3.5](/tpl/images/0490/7369/45766.png)
Hence, The mean weekly allowance is 3.5 dollars.
